S01:E02 - LRRP
There were no other units in Vietnam like the LRRPs. In fact, you probably had to go back to the American Revolution and the Civil War to find small units fighting a guerrilla war in enemy territory. There were some people who figured out right away that to fight this enemy we needed to put small, highly mobile reaction forces on the ground. To this end Colonel David Hackworth helped organize two volunteer platoons that they called Tiger Forces. These patrols consist of specially trained personnel capable of performing reconnaissance, surveillance and target acquisition within the dispatching unit's area of interest. Their goals: Track em, find em, and kill em. There were only thirteen independently operating LRRP (later Ranger) units in the whole country. There was no central command and control structure; they were only responsible to whatever command issued their orders.
