or reassign those perceived as less capable. McNair was promoted to temporary major general in September 1940, and temporary lieutenant general in June 1941. The War Department also assigned GHQ operational responsibilities, including planning for the defenses of facilities in Iceland, Greenland, and Alaska. McNair generally delegated the responsibility for this aspect of GHQ activities to his deputy, Brigadier General Harry J. Malony, so that he could concentrate on GHQ's organizational and training responsibilities, but maintained overall control of each role. McNair established the GHQ on the site of the Army War College (now the location of the National War College) at Washington Barracks (now Fort Lesley J. McNair), as the college had been closed for the duration of the war. McNair continued to command Army Ground Forces from this location rather than moving into the Pentagon when its construction was completed in 1943. Army Ground Forces AGF creation and operations In March 1942, the Army eliminated the General Headquarters in favor of three new functional commands: Army Ground Forces (AGF), commanded by McNair; the Army Air Forces (AAF), commanded by Lieutenant General Henry H. Arnold; and the Services of Supply (later the Army Service Forces or ASF), commanded by Lieutenant General Brehon B. Somervell. McNair's task at AGF was to expand the Army's ground forces from their March 1942 strength of 780,000 officers and men to more than 2.2 million by July 1943, and more than 8 million by 1945. His duties grew significantly, and included all Army boards, formal schools, training centers, and mobilization camps, as well as special activities having to do with the four combat arms (Infantry, Field Artillery, Cavalry, and Coast Artillery). As part of this reorganization, the Army eliminated the branch chief positions which had been responsible for these arms, transferring their authority to McNair. In addition, he had authority over four new "quasi-arms" which did not fall under the traditional combat arms – Airborne, Armor, Tank Destroyer, and Antiaircraft Artillery. The Army intended for this reorganization to end inter-branch rivalries and competition for pre-eminence and resources; in fact it met with mixed success as advocates for each branch continued to argue among themselves. Additionally, competition for authority and resources also emerged between the War Department General Staff and the three functional commands, and between the functional commands themselves. Used to working with minimal delegation, and functioning with a small staff, McNair largely concentrated
