The modern Army of Arabia has its roots in the Saudi state, which was dating to 1744, and is considered to be the birth year of the Saudi army. As of 1901 the ground forces was re-established as a separate branch of the armed forces with the starting of the modern Saudi state. and it is considered the oldest branches of the Saudi Arabia's military. Conscription lasted up until dissolved the War chancellery. Historically, the MoW was created to unify the armies of the state under one military power. It was existed until 1933, when it was renamed "Agency of Defence" under the Finance Minister administration as Agent. By 1944, the Agency was developed and incorporated into the Armed Forces Inspectorate. Other events that led to an expansion of the Saudi Army were the Arab–Israeli conflict in 1948, the fall of Shah Mohammad Reza Pahlavi in the Iranian Revolution in 1979 and the subsequent fears of possible hostile's actions, and as well as the Gulf War II in 1990. In the year 2000, Saudi Arabia's government spent billions of dollars to expand the Saudi military including the Army. The current minister of defense is Prince Mohammad bin Salman, who was appointed on 23 January 2015.

The Saudi expeditionary forces participated in a number of relatively minor clashes with the IDF between October 16-19, mostly in concert with the Jordanian 40th Armored Brigade.

The combat strength of the Saudi Army consists of 4 Armoured, 5 Mechanized, 2 Light Infantry Brigades. The Saudi Army deployed the 12th Armoured Brigade and 6th Mechanized Brigade at King Faisal Military City in the Tabuk area. It deployed the 4th Armoured Brigade, and 11th Mechanized Brigade at King Abdul Aziz Military City in the Khamis Mushayt area. It deployed the 20th Mechanized Brigade and 8th Mechanized Brigade at King Khalid Military City near Hafr al Batin. The 10th Mechanized Brigade is deployed at Sharawrah, which is near the border with Yemen and about 150 kilometers from Zamak. Despite the addition of a number of units and increased mobility achieved during the 1970s and 1980s, the army's personnel complement has expanded only moderately since a major buildup was launched in the late 1960s. The army has been chronically understrength, in the case of some units by an estimated 30 to 50 percent. These shortages have been aggravated by a relaxed policy that permitted considerable absenteeism and by a serious problem of retaining experienced technicians and noncommissioned officers. The continued existence of a separate national guard also limited the pool of potential army recruits. Armor
