Fort Benjamin Harrison was a U.S. Army post located in suburban Lawrence Township, Marion County, Indiana, northeast of Indianapolis, between 1906 and 1991.

[7] When the United States reestablished the Military Police Corps in 1941, an MP school was established at Camp Glenn and was in operation by early 1942.

[8] In 1947, the Army declared Fort Harrison to be surplus property,[9] but declined to completely close it due to a lack of adequate training space for the Indiana National Guard.

The Adjutant General School remained there until the Base Realignment resulted in its move to Fort Jackson, South Carolina, starting in 1991.

The Interservice Postal School was located at Fort Benjamin Harrison in the 1970s under the US Army Institute of Administration (USAIA), and was staffed by instructors from all four services.

With the movement and creation of a number of training classes in financial, clerical, and information technology (most notably the Programmer/Analyst Course and the Computer Machine Operator Course) the fort was given the derisive moniker "Uncle Ben's Rest Home" implying that no real military training took place there.

Fort Benjamin Harrison was closed as part of the 1991 Base Realignment and Closure Commission.

[14] On May 29, 2009, the Indiana National Guard held a ground-breaking ceremony for a new facility, the Lawrence Readiness Training Center, which opened in 2011.

It includes one and two-story Colonial Revival style brick buildings that were part of the original fort complex.
