By the end of World War II, two Army corps and elements of 10 divisions trained on the installation. The peak strength was 35,000 soldiers. During the Korean War, Fort A.P. Hill was again a major staging area for units deploying overseas, including the VII Corps Headquarters and the 3rd Armored Cavalry Regiment. The fort was the major center for Engineer Officer Candidate School training out of Fort Belvoir during the Korean War. Approximately 100,000 active and reserve troops from all components of the Department of Defense spend 600,000 training days annually at Fort A.P. Hill.
Engineers can practice demolition, construction and earthmoving.
There are also facilities to train soldiers for military operations in urban terrain, POW control and hostage rescue. Leased land along the Rappahannock River allows practice of various bridge and rafting operations. With its program of Integrated Training Area Management, A.P. Hill is able to match its training capabilities with the needs of the training customer. This enables the installation to assure that training does not overtax the capacity of the land or degrade environmental quality. Fort A.P. Hill is home of a Regional Support Center for ITAM, providing full Geographic Information System and technical support for 25 installations and technical support for 50 other installations east of the Mississippi River and in Europe.
