How many brigades are in the U.S. Army?
173rd Airborne Brigade Combat Team
The brigade arrived in Vietnam on 7 May 1965, the first major ground combat unit of the United States Army to serve in the country. Brigadier General Williamson boldly predicted on arrival that his men would defeat the Viet Cong quickly and that they "would be back in Okinawa by Christmas". The 1st Brigade, 101st Airborne Division; the 2nd Brigade, 1st Infantry Division; and the 1st Cavalry Division quickly followed the 173rd into Vietnam, the first of what would eventually be 25 U.S. Army brigades to serve in the country. As larger US Army commands were established in Vietnam, the brigade was assigned to the III Corps and II Corps tactical zone, which they would serve in for the next six years. The brigade was put under the command of II Field Force, Vietnam.
Brigade of the Guards
Currently the Brigade of the Guards consists of 19 regular battalions and 2 territorial battalions and 1 RR (rashtriye rifle) battalion. In the 1980s, the Indian Army began to increase the number of mechanized infantry battalions on its order of battle. As part of this program, the battalions of the Brigade of Guards were eventually converted to mechanized infantry.
