Army Strategic Command

 was situated at the Erskine Barracks in Fugglestone St Peter some 4 km North West of Salisbury in Wiltshire.

The site, which had been used by the United States Army as a field base during World War II, was acquired by the British Army for use as a headquarters for Southern Command in 1949. Named after General Sir George Erskine, the barracks went on to become the Headquarters of Army Strategic Command in 1968.

Army Strategic Command housed the office of Major General Oliver Hamilton of the Scots Guards, Colonel Lethbridge-Stewart's direct commander during The London Event and the events that followed. (TV: The Web of Fear, PROSE: The Ambush!, The Forgotten Son)
