81st Rangers group

The 81st Ranger Group was a unique unit originally formed as part of the Project DELTA reaction force. Formed on 1 November 1964 as the 91st Airborne Ranger Battalion and consisted of three companies of Montagnards. A fourth company was added in 1965. It was reorganized in 1966 as the 81st Ranger Battalion by the "purging of non-Vietnamese" to make it more "effective". The 81st consisted of six all-Vietnamese companies. It was officially under Army of the Republic of Vietnam Special Forces (LLDB) command and not that of Ranger Command. It was actually under the direct control of Project DELTA although two companies were made available to the LLDB.
