LRSD meaning in Governmental ?

The United States Army long range surveillance detachment (LRSD) is organized as a detachment organic to the military intelligence battalion at division level for the purpose of long-range surveillance. The LRSD's are organized into a headquarters section, communications section (two base radio stations), and six surveillance teams. (Light division LRS detachments only have four surveillance teams.) The leaders are airborne and Ranger qualified. All other personnel in the detachment are airborne qualified. Most active Army LRSDs were inactivated in September 2005, with the notable exceptions 173rd Airborne's LRSD which was deactivated in 2006 and the 82nd Airborne's LRSD, which was converted to Pathfinders in 2008, and most Army National Guard units were inactivated in September 2008; some were transferred to battlefield surveillance brigades and were reflagged and redesignated as Troop C within the brigade's cavalry squadron (reconnaissance and surveillance). For example, the 151st Infantry Detachment (LRS) of the 38th Infantry Division became Troop C (LRS), 2d Squadron, 152d Cavalry Regiment, 219th Battlefield Surveillance Brigade. Two new National Guard Long Range Surveillance Companies were stood up in September 2009.
