Khmer National Army


The Khmer National Army, commonly known as the "Cambodian Army", was the Land Component of the Khmer National Armed Forces, the official military of the Khmer Republic during the Cambodian Civil War between 1970 and 1975.

History

The oldest and largest branch of the Cambodian armed forces in terms of personnel and matériel, the Khmer Royal Army was officially created on 20 November 1946, after the signing of a French–Khmer military agreement which defined the provisional organization of both the ARK and the mixed French-Cambodian troops. The terms of the agreement stipulated that the new armed forces would consist of indigenous territorial units stationed within Cambodia to help maintain order and a mobile reserve comprising 8,000 Khmer soldiers, to be divided on equal halves of 4,000 each between the ARK and the mixed infantry units of the French Far East Expeditionary Corps, placed at the disposal of the French High Commissioner for Indochina. The formation and instruction of the ARK units was entrusted to a French Military Training Mission, staffed by French Army officers and NCOs, who acted as instructors and military advisers.
Three days later, the first entirely Cambodian regular military unit, the 1st Khmer Rifle Battalion, was raised by the French Military Mission in Phnom Penh, formed by elements transferred from both the Khmer National Guard or "Indigenous Guard" and the Cambodian Rifle Regiment, comprising three rifle battalions, of the colonial French Union Army. A second rifle battalion, created out from locally recruited Khmer irregular auxiliaries was raised at Kratie in December that year. Both battalions were posted to the mobile reserve in January 1947.
Led by a cadre of French officers and senior NCOs, and intended to be used on internal security operations to reinforce CEFEO regular troops, the new Khmer battalions saw their first combat in 1947 against Vietminh guerrilla forces in north-eastern Cambodia. Small-scale counter-insurgency operations, this time against the Cambodian nationalist Khmer Issarak rebel movement, continued over the next three years, during which the Khmer battalions gradually assumed responsibility for the defence of Battambang and Kampong Thom Provinces, which had been part of the territory returned to Cambodia by Thailand in early 1947.

The ARK in the First Indochina War

This period saw a rapid expansion of ARK units and by January 1947, its effective strength stood at about 4,000 men, of which 3,000 served in the Khmer National Guard. In July 1949, a second French–Khmer military agreement was signed, granting Cambodian military forces further operational autonomy in the Siem Reap and Kampong Thom provinces. Under an additional protocol signed in June 1950, Cambodian provincial governors were assigned the responsibility for the pacification of the provinces under their jurisdictions; to accomplish this mission they were given each a counter-insurgency force consisting of one independent Khmer infantry company. Late that year, a military assistance agreement was signed between the United States and France, which provided for the expansion of indigenous military forces in Indochina, and by 1952 ARK strength had reached 13,000 men, outnumbering the French CEFEO forces stationed in Cambodia. New Khmer rifle battalions were formed, specialized combat-support units were established, and a framework for logistical support was set up.
A third Rifle Battalion was raised in August 1948 at Takéo, followed in January 1951 by other two rifle battalions at the French-run Pursat Infantry Training Centre. Two armoured car squadrons were formed, the 1st Reconnaissance Squadron in August 1950 and the 2nd Reconnaissance Squadron in July 1951 at Phnom Penh, and a Khmer Parachute Battalion was officially created in December 1952. Two additional infantry battalions were raised in April 1953 – 7th BCK in Siem Reap and 8th BCK at Ta Khmao in Kandal Province, bringing total strength up to 6,000 men, with about half serving in the Khmer National Guard and half in the mobile reserve. The latter at this time comprised three rifle battalions, with one of its battalions been allocated to French Union forces elsewhere in Indochina. Cambodian military units were given wider responsibility, including the protection of the rubber plantations along the middle Mekong River region, and surveillance of the coastal areas of the southern Cambodian provinces and of the eastern border areas with Cochinchina to prevent infiltration attempts by Vietminh guerrilla units.
Although French-trained Khmer junior officers and NCOs slowly began to take a leading role over time, the ARK was still kept firmly under the control of the French High Command through its military training mission, renamed in 1951 "French Military Mission to the Government of Cambodia". The ARK General Staff was filled entirely by French senior and intermediate rank officers, who did most of the command-and-control support, intelligence work and training, and supervised weaponry and equipment deliveries to the Khmer military units. By mid-1953, however, at the instigation of their youthful King Norodom Sihanouk, Khmer military personnel began not only to participate in anti-French nationalistic demonstrations calling for complete Cambodian independence, but they also deserted French-led units by the hundreds. Following a world tour to publicize his campaign for independence, King Sihanouk retired to a "free zone of independence" set up at Battambang Province, where he was soon joined by 30,000 ARK troops and Police in a show of support and strength. In October that year, the French High Command finally agreed to transfer responsibility for Cambodian national security to the ARK and for that effect, another French-Khmer military agreement was signed. Under the terms of this agreement, the French-led Khmer military units were to be transferred to the control of the Cambodian national authorities, and that an operational zone was to be created in the east bank of the Mekong and assigned to the French Union forces. The latter was held jointly by the French Lower Mekong Operational Group and ARK units, which provided security to the entire length of Route 13 inside Cambodia. The only elements that remained subordinated to the French Commander-in-Chief in Cambodia were the Military Mission and the GOBM. The ARK and the Khmer National Guard were consolidated into a new national defense force comprising 17,000 men, the Cambodian National Armed Forces. At this stage the FANC consisted of ground forces only, although plans were being laid by the French for the creation in a foreseeable future of Air and Naval components.
On 9 November 1953, the Kingdom of Cambodia officially proclaimed its independence from France. Meanwhile, the expansion of the newly created FANC continued with the addition that same month of two new light infantry battalions, the 9th BCK raised in Svay Rieng and the 10th BCK at Prey Veng. The Kingdom of Cambodia was granted full independence on 20 November and King Sihanouk officially took command of the 17,000-strong FANC, though France maintained the right to station CEFEO units in north-eastern Cambodia to guard its communications links with Tonkin.
In early 1954, the "Khmerization" of the FANC units still under the command of French officers and NCOs began to be implemented, with most of these cadres assuming the roles of technical advisors or instructors, while others kept their posts in the various unit headquarters' staffs and technical branch services. However, due to the lack of a clear development plan for the FANC, and to compensate for the shortages of trained officers, its officer corps was expanded by replacing the departing French cadres with poorly-trained Khmer reserve officers, who were simply incorporated into the active duty officers' and NCO corps. Certain Khmer reserve officers were placed in the territorial commands, while the upper echelons of command were filled by Khmer senior civil servants hastily commissioned as military officers, whose grade was based on their civilian rank. In this system, a provincial governor or the president of a tribunal could become a Lieutenant colonel or Colonel without having ever received military training of any sort.
The FANC continued to expand in the following months to accommodate new ground units and branches of service. An autonomous Cambodian armored battalion was set up by the French, equipped with US armored cars, half-tracks and scout cars, and a naval and riverine service, the Royal Khmer Navy was officially established on 1 March. By April 1954, the FANC consisted of ground and naval branches, with the former reverting to its original designation of Khmer Royal Army.

The neutrality years 1964–1970

In response to the coup against President Ngô Đình Diệm in South Vietnam, Prince Sihanouk cancelled on 20 November 1963 all American aid, and on 15 January 1964 the US MAAG aid program was suspended when Cambodia adopted a neutrality policy. The ARK continued to rely on French military assistance but at the same time turned to the Soviet Union, China, Czechoslovakia, Britain, Belgium, and West Germany for weapons, equipment and training.

Pre-1970 organization

By January 1970, the Royal Khmer Army stood at about 35,000 Officers and enlisted men and women, organized according to the French Army model into 53 regiments and 13–15 regional independent companies; slightly over half were designated infantry battalions, and the remainder light infantry battalions and border commando battalions. Elite troops and some support units, including the Khmer Royal Guard, Phnom Penh garrison, Airborne troops, Signals, Engineers, Artillery, Anti-Aircraft, and Transport were organized into six larger formations termed Half-Brigades. Other technical branch services such as Medical, Military logistics, , Military Fuel/Petrol, Oil and Lubricants – POL, Quartermaster, Military Police, Military Justice, Social and Cultural Services, Geographic Services, and Veterinary Services were placed under the responsibility of the Service Directorates subordinated to the Ministry of National Defense.
Cambodia was divided since September 1969 into seven military districts termed "Military Regions" – MRs encompassing one to ten military sub-districts of unequal size roughly corresponding to the areas of the country's 23 provinces and districts. They comprised the 1st MR, 2nd MR, 3rd MR, 4th MR, 5th MR, and 6th MR.
Most ARK units were concentrated in the northeast at Ratanakiri Province and on the Phnom Penh area; the latter was the headquarters of the six main Half-Brigades and supporting services whereas infantry formations were deployed throughout the country. The small armoured corps was also organized into an Armoured Half-Brigade consisting of two independent tank battalions – one stationed at Phnom Penh and the other at Kampong Cham – and an armoured reconnaissance regiment, 1st ARR at Sre Khlong in Kampong Speu Province.
Although a sizeable reserve cadre of trained Officers and NCOs did existed, there was a persistent lack of reserve units. Some units were posted to the General reserve forces, which consisted merely of the Phnom Penh garrison troops – a half-brigade made of two light infantry battalions – and the combat support units.

Weapons and equipment

With the exception of a few specialized units, most of these formations actually fell below strength, were poorly trained and equipped in a haphazard way with an array of French, American, British, Belgian, West German, Czechoslovakian, Chinese, and Soviet weapon systems.
During the First Indochina War, ARK Infantry battalions were issued with WWII-vintage MAS-36, M1903 Springfield, and Lee–Enfield bolt-action rifles, along with Sten, M1A1 Thompson, and MAT-49 submachine guns; FM 24/29, Bren, and M1918A2 BAR light machine guns were used as squad weapons. Officers and NCOs received MAS-35-S, FN P35 or Colt.45 M1911A1 pistols. In September 1950, the ARK began the process of standardisation on US equipment, with infantry and airborne units taking delivery of the M1 Garand semi-automatic rifle, the M1/M2 Carbine, and the M3A1 Grease Gun, followed by the Browning M1919A4.30 Cal Medium machine gun and Browning M2HB.50 Cal Heavy machine gun. After US military assistance was renounced in 1964, the ARK received from China, the Soviet Union and other Eastern Bloc countries substantial numbers of the SKS semi-automatic rifle, Vz. 58 assault rifle, AK-47 assault rifle, DP light machine gun, RPD light machine gun, SG-43/SGM Goryunov medium machine gun, and RPG-2 and RPG-7 anti-tank rocket launchers. In addition, limited quantities of FN FAL and Heckler & Koch G3 assault rifles were reportedly acquired from Belgium and West Germany, but they were never adopted as standard weapons. ARK infantry and airborne formations were also equipped with crew-served weapons such as Brandt mle 27/31 81mm and M2 4.2-inch Mortars.
The armoured corps inventory consisted of thirty-six M24 Chaffee light tanks, forty AMX-13 light tanks, and some M8 HMC 75mm self-propelled Howitzers; reconnaissance squadrons were provided with five M8 Greyhound light armoured cars, fifteen M20 Armoured Utility Cars, fifteen Panhard AML-60 and AML-90 armoured cars. Mechanized infantry battalions were issued with M2 half-track cars, M3 Half-Tracks, fifteen M3A1 Scout Cars, BTR-40 and thirty BTR-152 armoured personnel carriers.
The artillery corps fielded M101A1 105mm towed field howitzers, twelve Soviet M-30 122mm howitzers, twenty Soviet BM-13 132mm and ten BM-14 140mm MBRLs.
Air Defense units were equipped with British-made Bofors 40mm L/60 anti-aircraft guns, twenty-seven Soviet AZP S-60 57mm anti-aircraft guns, Chinese Type 55/65 37mm anti-aircraft guns, and eight Soviet KS-19 100mm air defense guns.
Logistics were the responsibility of the transport corps, equipped with a variety of liaison and transportation vehicles. The motor pool consisted in a mixed inventory totalling 150 vehicles, including WWII-vintage US Willys MB ¼-ton jeeps, Land Rover Series II, Soviet GAZ-69A light trucks and GAZ-63 2-ton trucks. Heavier transport vehicles ranged from ex-French Army WWII-vintage US GMC CCKW 2½ ton and Chevrolet G506 1½ ton trucks to Chinese Yuejin NJ-130 2.5 ton trucks and Jiefang CA-30 general purpose 2.5 ton trucks.

Expansion 1970–71

Following the March 1970 coup, the new Head of State Marshal Lon Nol issued a general mobilization order and, after securing American, Thai and South Vietnamese military support, promptly set up ambitious plans to expand the Cambodian armed forces. Shortly after the coup, however, China and the Soviet Union severed their military assistance programs, and the French military mission suspended all cooperation with Cambodia, thus depriving its Army of vital training and technical assistance. By June 1970, the rechristened Khmer National Army, had rapidly expanded to 110,000 men and women, though most of them were untrained raw recruits organized into a confusing array of French- and American-modelled combat formations, staffed by elderly NCOs and inexperienced young officers.
At the same time, there were several changes regarding field organization. Regular infantry battalions were at first amalgamated into autonomous regiments, soon abolished in favour of a brigade grouping several battalions. By early May 1970, eighteen new Infantry Brigades had been created, but only twelve – the 1st, 2nd, 3rd, 4th, 5th, 6th, 7th, 8th, 9th, 10th, 11th, 12th, 13th, and 14th Inf. Bdes – were properly manned, the other six – 15th, 16th, 17th, 18th, 19th, and 20th Inf. Bdes – were never brought to strength or remained on paper.
From mid-1970, Infantry units began to be formed into larger 15 Brigade Groups, each comprising two brigades and roughly the size of a Division, but lacking support units. Of these, only three were military effective by January 1972, other three were still undergoing training, and the remaining nine were only marginally reliable. The Artillery, Signals, Engineer, Transport, and Armoured Half-Brigades were also brought to brigade strength, with the latter becoming the 1st Khmer Armoured Brigade.

Re-organization 1972–73

To streamline the mass of ground forces' combat formations, a major reshuffle was implemented between July and December 1972 along American lines. The old organizational structure modelled after the French Army was abandoned in favour of a modern conventional organization based on the US Army model. By January 1973, all brigade group headquarters, 17 regimental HQs, 16 brigade HQs, and 13 battalions had been dissolved, replaced by newly created 32 infantry brigades, 202 infantry battalions, and 465 territorial infantry companies. Out of these totals, 128 battalions formed the maneuver elements for the 32 brigades, of which 20 would remain independent and 12 were to be distributed among new four Mechanized Infantry Divisions created from existing Brigade Groups:
A fifth division, the understrength 9th Guards Division was later raised in April 1974. The Armour, Artillery, Signals, Transport, and Engineer arms were left untouched by this reorganization and retained their separate brigade structure under their own commands. The General Reserve was also reorganized by Marshal Lon Nol in April 1972 by sub-dividing it into three groups: the Forces A, attached to a MR for combat operations; Forces B, the General Staff reserve comprising five brigades; and Forces C, two airborne battalions under the personal command of Lon Nol. The ANK order-of-battle by mid-1973 consisted of four infantry divisions, nine independent infantry brigades, two airborne brigades, one armored brigade, one Lake Brigade, one battalion-sized Special Forces unit, five support services' brigades, 15 regional infantry brigades attached to the Military Regions, and one air defense half-brigade. Territorial units included 58 infantry battalions assigned to each of the military sub-districts within the larger MRs, 529 independent infantry companies, and 76 field artillery batteries.

Weapons and equipment 1970–75

Cambodian army strength stood at 220,000–230,000 troops on paper by mid-1972, but is estimated that the actual number was no less than 150,000, armed by the United States with US$1.18 billion-worth of weaponry and equipment. Its inventory included 241,630 rifles, 7,079 machine guns, 2,726 mortars, 20,481 grenade launchers, 304 recoilless rifles, 289 howitzers, 202 M113 armoured personnel carriers and 4,316 trucks.
In the early months of the War, most Cambodian infantry units fought the People's Army of Vietnam and Khmer Rouge with a mix of surplus World War II-vintage French and U.S. and modern Soviet and Chinese infantry weapons either inherited from Khmer Royal Army stocks or delivered as emergency aid by the Americans. ANK infantry battalions later sent to South Vietnam for retraining between February 1971 and November 1972 under the US Army-Vietnam Individual Training Program were issued Smith & Wesson Model 10 revolvers, Colt.45 M1911A1 and Smith & Wesson Model 39 pistols, M16A1 assault rifles, M1918A2 BAR light machine guns, Browning M1919A4.30 Cal medium machine guns, Browning M2HB.50 Cal heavy machine guns, M79 grenade launchers, M72 LAW Anti-tank rocket launchers, M19 60mm and M29 81mm mortars and M40A1 106mm recoilless rifles. Limited quantities of the CAR-15 carbine, the M60 machine gun and the M203 grenade launcher were also provided to the ANK, eventually finding their way into Cambodian elite troops, such as the Khmer Special Forces and the Recondo companies. Although the UITG and MEDTC aid programmes allowed the ANK to standardise on modern U.S. weapons, they never superseded entirely the earlier weaponry, particularly in the case of the territorial units and rear-echelon support formations.
In October 1970, the ANK command sought to expand its armoured corps but, despite repeated requests for the delivery of more modern M41 Walker Bulldog light tanks and M-706 armoured cars, their requests were declined by Washington. Thus Cambodian armoured units continued to rely on their ageing fleet of US M24 and French AMX-13 light tanks and M8, M20 and AML armoured cars until 1974, when mounting combat losses and maintenance problems forced the withdrawal of most of these vehicles from frontline service, being gradually replaced by M113 APCs.
The ANK also received after 1970 a new influx of much-needed softskin transport and liaison vehicles. Early in the War, the Army Command was confronted with a serious logistical problem – the small number of outdated US, Soviet, and Chinese military trucks available from its transport corps soon proved insufficient to carry the increasing number of troops mobilized, let alone resupplying them over long distances. To remedy the inequities of its transportation system during the first year of the War, Army field commanders resorted to commandeering civilian buses and other commercial vehicles to get their troops to the front. In 1971–72, the transport corps was re-organized and expanded with the help of the US and Australia, who provided 350 M151A1 ¼-ton utility trucks, Dodge M37 ¾-ton 1953 utility trucks, and M35A1 2½-ton cargo trucks, followed by 300 militarized GMC/Chevrolet C-50 medium-duty commercial trucks assembled in Australian plants.
The Artillery Corps was also re-structured under US lines in 1972–73, receiving additional twenty-five M101A1 105mm towed field howitzers, ten M114A1 155mm towed field howitzers and eight tracked M109 155mm self-propelled guns, meant to replace the Soviet artillery pieces gradually withdrawn from service due to a lack of spare parts and ammunition.

Elite Forces

Final operations 1974–75

On 17 April 1975 the Khmer Rouge entered Phnom Penh, bringing the Cambodian Civil War to an end. Long Boret, Lon Non and other FANK senior staff officers and top officials of the Khmer Republic government were summarily executed without trial at the Cércle Sportive complex, while Army troops in the city were disarmed, being subsequently taken to the Olympic Stadium and executed as well.
The same fate befell on the remaining Cambodian Army units and garrisons still holding on to the provincial capitals and some key towns. Throughout the country, thousands of demoralized Cambodian men and women who had the misfortune of being captured wearing the Army uniform – ranging from officers to NCOs, and even ordinary soldiers, regardless if they had committed any war crimes or not – were rounded up by Khmer Rouge guerrilla units and massacred. In Phnom Penh and elsewhere, some officers and enlisted men narrowly avoided capture by quickly changing to civilian clothes and went into hiding. While scores of surrendering Cambodian soldiers were simply shot by firing squad and had their bodies dumped into shallow graves dug in forest areas, a considerable number of them were sent to be 're-educated' in the new labor camps promptly set up by the Khmer Rouge shortly after their victory, where they were forced to endure the camps' terrible living and working conditions until the 1978–79 Cambodian–Vietnamese War. Only a few Army personnel in April–May 1975 escaped by foot or by vehicle across the border into Thailand, where in the late 1970s they would provide the founding cadre for the anti-Vietnamese Sihanoukist National Army and Khmer People's National Liberation Front guerrilla forces.

Cambodian Army uniforms and insignia

The Cambodian Army owed its origin and traditions to the Khmer colonial ARK and CEFEO troops on French service of the First Indochina War, and even after the United States took the role as the main foreign sponsor for the Khmer National Armed Forces at the beginning of the 1970s, French military influence was still perceptible in their uniforms and insignia.

Service dress and field uniforms

The basic Royal Cambodian Army work uniform for all-ranks was a local copy of the French Army's tropical working dress, consisting of a light khaki cotton shirt and pants modelled after the WWII US Army tropical "Chino" khaki working dress. The M1945 shirt had a six-buttoned front, two patch breast pockets closed by clip-cornered straight flaps and shoulder straps whilst the M1945 "Chino" pants featured two pleats at the front hips. In alternative, the short-sleeved M1946, which featured two pleated breast pockets closed by pointed flaps or the "Chino"-style M1949 shirts could be worn; a long-sleeved version also existed, based on the French M1948 shirt.
Shorts were also issued and worn according to weather conditions. In the field, Cambodian officers and enlisted men wore French all-arms M1947 drab green fatigues.
ARK Officers received the standard FARK summer service dress uniform in khaki cotton, which was patterned after the French Army M1946/56 khaki dress uniform ; for formal occasions, a light summer version in white cotton was also issued. The open-collar jacket had two pleated breast pockets closed by pointed flaps and two unpleated at the side closed by straight ones whilst the sleeves had false turnbacks; the front fly and pocket flaps were secured by gilt buttons. The uniform was worn with a matching Khaki shirt and black tie on service dress whereas the white version was worn with a white shirt and a black tie instead.
After March 1970, as part of the US-sponsored MAP re-equipment program, the Cambodian Army was supplied with new American olive green tropical uniforms, the US Army OG-107 utilities and the M1967 Jungle Utility Uniform which quickly replaced the older ARK khaki working uniform and the drab green French fatigue clothing.
As with the ARVN, the Cambodians soon produced their own interesting variety of versions of these jungle utilities or had tailors to modify them to suit their tastes and needs, with mix-and-match combinations being far from uncommon. It was not infrequent to see Cambodian male and female soldiers wearing an OG-107 shirt accompanied by a pair of M1967 Jungle Utility trousers or vice versa. The OG-107 trousers were often converted by the addition of cargo pouches; shirts and jackets had their sleeves cut at elbow level, shoulder straps were added, single-buttoned pocket flaps could be replaced by two-button versions or concealed ones, and – a common practice for officers – the addition of a shoulder pocket on the upper left sleeve for ballpoint pens, which were the symbol of authority in Indo-Chinese armed forces. Sometimes fatigue shirts were converted into light bush jackets by adding two-buttoned patch pockets on the lower skirt. Olive green US M-1951 field jackets were also issued to all-ranks.
Reflecting the increasing American influence, ANK senior officers adopted in 1970–71 a new dress uniform, which consisted of an Olive Green tunic and slacks worn with a white shirt and black tie. The cut of the four-buttoned tunic was a hybrid design resembling both the US Army M-1954 "Class A" green dress and the earlier French-style M1946/56 khaki dress; it had two pleated breast pockets closed by pointed flaps and two unpleated at the side closed by straight ones whilst the sleeves had false turnbacks. The front fly and pocket flaps were secured by gilt buttons bearing the combined service emblem of the FANK General Headquarters.
Female personnel were issued a service and working olive green OG-107-style short-sleeved blouse based on their male counterparts' versions, provided with two patch breast pockets closed by straight or pointed flaps and shoulder straps. The blouse was worn with a matching service and working olive green knee-length skirt.

Camouflage uniforms

French "Lizard" camouflage M1947/51, M1947/52 and M1947/53-54 TAP jump-smocks and M1947/52 TTA vests with matching trousers were issued to ARK airborne troops since the 1950s, though later shortages in the early 1970s limited its use to officers and NCOs only. Enlisted-rank paratroopers received a locally produced spotted camouflage uniform during the 1960s, which consisted of olive green and russet blotches on a pale green background.
After 1970, "Highland" and Tigerstripe patterns of US, Thailand, and South Vietnamese origin were also provided to the ANK. Cambodian students that attended the Para-Commando course at the Batujajar Airborne Commando School, near Bandung in Indonesia between March–November 1972, received the Indonesian Army's "flowing blood" camouflage fatigues.

Headgear

The most common headgear for ARK/ANK all-ranks was a lightweight beret made of light khaki cotton cloth surnamed the "gourka", adopted by the French Army as the M1946 during the First Indochina War, who copied it from a tropical beret pattern previously worn by British troops in the Far East during WWII.
Berets were worn pulled to the left in French fashion, with the colour sequence as follows: General Service – Light Khaki, Infantry – Light Olive Drab, Armoured Corps – Black, Paratroopers and Para-Commandos – Cherry-red, Special Forces – Forest Green, Military Police and Regional Gendarmerie – Dark Blue; berets made of "Tigerstripe" and "Highland" camouflage cloth were also issued to elite units. With the exception of the light khaki and camouflage versions – which were manufactured in three pieces –, all other corps' berets were made of wool in a single piece attached to a black leather rim provided with two black tightening straps at the back, following the French M1946 or M1953/59 models. French M1946 and M1957 light khaki sidecaps were also adopted by the ARK, but seldom used.
ARK officers received a light khaki service peaked cap based on the French M1927 pattern to wear with the khaki service dress, whilst a white summer top version was worn with the FARK white full dress uniform.
After March 1970 these caps were replaced by an Olive Green version – incidentally, the change of colour made it to resemble more the US M1954 Visor Cap – for wear with the new Americanized dress uniform adopted by the ANK. An olive green sidecap was adopted by female personnel to wear with their Olive Green service and working uniform.
In the field, ARK officers and enlisted men wore a mixture of light khaki tropical berets, US M-1951 cotton field caps, French M1949 bush hats and privately purchased civilian sun hats in white, Khaki or OG cotton cloth. Later, a khaki patrol cap resembling a simplified baseball cap version was adopted as the standard ANK fatigue headgear for all-ranks, though the South Vietnamese ARVN fatigue cap in OG cotton cloth, whose shape recalled the US Marines utility cap, was sometimes seen. In addition, a wide range of OG or camouflage jungle hats and baseball caps also found their way into the ANK from the US, South Vietnam and Thailand though they never displaced entirely the earlier headgear. Period photos do show that the old French bush hat remained popular with the troops, who also wore Cambodian- or South Vietnamese-made versions in camouflage cloth.
Steel helmets, in the form of the US M-1 and French M1951 NATO models were standard issue in the ARK, with paratroopers receiving either the US M-1C jump helmet and its respective French-modified versions or the French M1951 TAP variant.
During the Republic, the ANK standardized on the M-1 model 1964 provided with the US Army Mitchell "Clouds" camouflage pattern cover, though some units retained the older US and French steel helmets throughout the war.
ARK armoured crews received the French M1951 and M1958/65 dark olive green leather crash helmets ; after 1970, Cambodian M113 APC crewmen were issued the US Combat Vehicle Crew fibreglass "bone dome" helmet, though neither models offered any satisfactory protection against shrapnel or small arms rounds.

Footwear

White low laced leather shoes were worn with the FARK white cotton full dress, with brown shoes being prescribed to wear with the khaki working uniform, and later, black ones with the new ANK OG dress uniform.
On the field, all Army personnel wore brown leather US M-1943 Combat Service Boots and French M1953 "Rangers" or French canvas-and-rubber Pataugas tropical boots, and sandals; paratroopers received the calf-length French M1950 or M1950/53 TAP black leather jump-boot models.
After 1970, the ANK standardized on the American black leather M-1967 model with "ripple" pattern rubbler sole and Jungle boots, and South Vietnamese Bata tropical boots, which replaced much of the older combat footwear.

Army Ranks

In deep contrast to the South Vietnamese ARVN and Laotian FAR, who replaced the French-style military ranks previously worn during the colonial period with their own devised rank insignia after 1954, the standard FARK rank chart continued to follow closely the French pattern. The Cambodian Armed Forces' system of military ranks was almost identical to the sequence laid out by the French Army 1956 regulations and common to all branches of service, differing only in some details.
Removable stiffened shoulder boards were worn by officers on their dress uniforms as per in the French practice, except that Cambodian Generals’ wore their stars above gold laurel-like leaf embroidery on the outer edge, and a miniature royal coat-of-arms featuring a combined crown-and-crossed spears device was incorporated on the inner end of the shoulder boards for all-ranks. The colour sequence of the FARK shoulder boards also varied according to the arm of service: general service – very dark blue or black; airborne troops – light green; medical corps – maroon.
On both the khaki working and olive green field uniforms, Generals' and senior officers' ranks were usually worn on shoulder strap slides but, if the issued combat jacket or shirt was not provided with buttoned shoulder straps, a single chest tab pinned to the front fly following French practice could be worn instead. As for senior and junior NCOs, they wore metal or cloth chevrons pinned to the chest; NCOs serving in combat units were entitled to wear their chevrons pointed upwards whereas their counterparts assigned to non-combatant, rear-echelon support formations had to wear their chevrons pointed downwards. Privates wore no insignia.
This basic system was maintained during the Republic, though standard black shoulder boards without the royal crest were adopted in 1970 for all services and from 1972 onwards some Cambodian officers began wearing metal pin-on collar rank insignia, obviously inspired by American practice. Although the system of military ranks remained unchanged, the rank of Field Marshal was created in 1970 for the President of the Khmer Republic and FANK Commander-in-Chief Lon Nol.

Branch insignia

ARK skill and trade badges came in gilt metal and/or ennamelled pin-on versions, with cloth embroidered yellow or black-on-green subdued variants being introduced after 1970. On dress and service uniforms, they were worn on both collars by all-ranks if shoulder boards were worn, but in the field officers did not wore them on the shirt collars if metal pin-on collar rank insignia was being worn; enlisted ranks usually wore branch insignia on both collars.

Unit insignia

Full-color and subdued nametapes were occasionally worn above the right shirt or jacket pocket on field dress; plastic nameplates were worn with the service and dress uniforms.
