Army of the Republic of Vietnam ARVN Mechanized Rifle Squadron, 1962

South Vietnamese M113 armored personnel carrier.

In 1962, the two existing ARVN Mechanized Rifle Companies were redesignated the 4th and 5th Mechanized Rifle Squadrons of the 2nd Armored Cavalry Regiment (ARVN). As more M113 APCs and M114 reconnaissance vehicles became available in late 1962, all four ARVN armored cavalry regiments were similarly reorganized. The ARVN mechanized rifle squadron was organized like a US mechanized infantry company, but it adopted different tactics. Previous combat experience of the ARVN Mechanized Rifle Companies indicated that the American doctrine of mounted and dismounted mechanized infantry combat was bound to fail in Vietnam, because attacks tended to bog down when the infantry dismounted. As a result, ARVN mechanized infantry squadrons adopted armored tactics and fought mounted. In 1967, ARVN cavalry troops adopted the organisation of tank troops with five armored fighting vehicles each.
