Guerrilla USA

Somewhere in the rugged countryside of West Virginia, men of the US Army's 7th Special Forces Group conduct an unconventional warfare exercise against an "Aggressor." Their mission? Infiltrate the fictional country of Easton, organize local guerilla forces, and conduct offensive operations against the enemy. 

This film produced by the US Army Pictorial Center in 1963 shows the type of unconventional warfare tactics and techniques that are still tested in the "Robin Sage" exercise that prospective Special Forces soldiers must pass in order to earn the right to don the coveted Green Beret.
