Army Support

The army unit that currently runs communications for the RRMC is the 114th Signal Battalion.

The army support unit for the RRMC has been moved around the army hierarchy several times.

• Between 1953 and 1971, it reported directly to the army's Joint Support Command.
• In 1971, as part of the Strategic Communications Command move to Fort Ritchie, the communications unit was redesignated as the Directorate of Telecommunications, and placed under the Fort Ritchie garrison commander.
• In 1976, the unit was redesignated the USACC Site R Telecommunications Center, a direct reporting element to the 7th Signal Command.
• In 1978, the unit was moved back under the command of the Fort Ritchie garrison, as the Directorate of Telecommunications.
• In October 1981, USACC Site R Telecommunications Center was reorganized and redesignated as USACC Site R under Headquarters, 7th Signal Command.
• In May 1984, USACC Site R was redesignated as USAISC-Site R, remaining as a direct reporting unit to 7th Signal Command.
• In October 1988, USAISC-Site R was redesignated as the 1111th U.S. Army Signal Battalion and placed under the 1101st U.S. Army Signal Brigade, Fort Lesley J. McNair, Washington, D.C., as the Army support battalion responsible for the maintenance, upkeep and communications of the AJCC Site R.
• In October 1993, the 1111th U.S. Army Signal Battalion was placed under the 1108th U.S. Army Signal Brigade, Fort Ritchie, Maryland. Most base operations activities were removed from the battalion’s mission, leaving communications as the primary unit mission.
• The 1995 Base Realignment and Closure Commission directed the relocation of U.S. Army Signal Command units and some Base Operations support personnel from Fort Ritchie to Fort Detrick, which became the home of East Coast long-haul communications. These units included the 21st Signal Brigade (formerly the 1108th U.S. Army Signal Brigade), the 114th Signal Battalion (formerly the 1111th U.S. Army Signal Battalion) and Information Systems Engineering Command-Continental United States. The 1110th U.S. Army Signal Battalion, already at Fort Detrick, is now the 302nd Signal Battalion and is assigned to the 21st Signal Brigade. More than 1,140 military members and civilian employees were transferred under the order. Site R and its personnel came under control of the Fort Detrick commander October 1, 1997. The actual movement of units began October 1, 1996, and Fort Ritchie was closed by September 30, 1998, well ahead of schedule.

The site has been declared part of the Pentagon Reservation per 10 U.S.C. § 2674(g).
