Sexual potency training, Special Forces (Vietnam 1970)

This is classified footage just released showing special forces participating in sexual potency training. They wanted to make sure all their soldiers were fit for battle and healthy in every way. They would line up a row of hot street babes and let the soldiers make their way down the line, fucking each one. If they lost their erection of came before they made it through the lineup, then they would fail the test. War is serious business.
