In 1979 Warner assumed his duties as the Commander in Chief, Readiness Command, headquartered at MacDill Air Force Base in Tampa, Florida. His tenure as REDCOM commander coincided with the interservice debate over which unified command should have jurisdiction over the Middle East and the associated Rapid Deployment Force. In 1980, the Rapid Deployment Joint Task Force was created under the command of Marine Lieutenant General Paul X. Kelley and based at MacDill Air Force Base. During planning and training exercises in the United States, the RDJTF reported to REDCOM, which was responsible for preparing United States-based Army and Air Force units for overseas deployment, but during operations the force was controlled by whichever headquarters had oversight over the territory in which it was deployed. Since the RDJTF was expected to operate mainly in the Middle East, permanent operational control over the force implied geographical responsibility for Southwest Asia. At the time, no unified command was specifically responsible for that increasingly critical region, which was divided between United States European Command and United States Pacific Command. Warner opposed proposals to assign the RDJTF to either European or Pacific Command, or to allow the RDJTF to oversee the Middle East as an autonomous command. Instead he asked that the land responsibility for Southwest Asia be returned to Readiness Command, which had overseen the Middle East and sub-Saharan Africa in its previous incarnation as United States Strike Command. Meanwhile, he insisted that as long as the RDJTF was headquartered in the United States, REDCOM was its governing unified command and the RDJTF should not continue to bypass the REDCOM commander by maintaining an independent office in Washington, D.C. The interservice controversy over which unified command should control the RDJTF created friction between the REDCOM and RDJTF headquarters staffs and eventually spilled into the press, which cast the debate as a personal feud between Warner and Kelley. "Unfortunately, we were both caught up in the service argument as to whether it should be a premier Army or Marine force," Warner said. On April 25, 1981, Secretary of DefenseCaspar Weinberger announced that the RDJTF would become a separate command with responsibility for Southwest Asia. Rebuffed in his attempt to renew the mandate of his command, Warner requested retirement, citing a lack of support from the Joint Chiefs of Staff during the debate. In parting, he observed that if the RDJTF were to be made an independent unified command, then REDCOM would be redundant and should be disestablished. The RDJTF became United States Central Command in 1983 and REDCOM was replaced by United States Special Operations Command in 1987.
Post-military
Warner retired from the Army on July 31, 1981. Subsequently, Warner was Vice President of Applied Technology, Vertex Systems, Incorporated, and later established V.F. Warner and Associates, a Washington-based consulting firm. He resided in McLean, Virginia.
While serving as Chief of Staff to the 82nd Airborne Division, Warner was seconded to the White House by General Alexander Haig, then Chief of Staff to President Nixon. Warner was to serve as the senior federal representative to address the standoff at the Pine Ridge Indian Reservation. Warner successfully resolved the issue without blood shed. Attorney Kenneth Tilsen, representing the American Indian Movement, commented that "Warner was the only one who really knew what he was doing...".
Boots on the ground
Warner is credited with coining the phrase "", to mean the actual forces engaged in a conflict. The first use of the phrase is identified as a quote in the Christian Science Monitor in reference to the Iran hostage crisis: "US options grow more difficults as the chance of a Soviet response increases. However, many American strategists now argue that even light, token US land forces -- 'getting US combat boots on the ground' as General Warner puts it -- would signal to an enemy that the US is physically guarding the area and can only be dislodged at the risk of war."
