Legion Assault

 is a unarmed perk in Fallout: New Vegas.

Requirements
It is acquired by talking to Lucius in Caesar's Tent with 50 Unarmed. Magazines and books can help you get your unarmed up, however if you are still struggling a buffout might just tip you over the 50 point mark.

Effects
Perform a power attack while running forward to perform the Legion Assault. When performing this move in third person, the PC runs forward, leaps into the air, and thrusts his right palm forward before landing back on the ground.
