Commando

Commando is a Fallout 3 Perk.

While using a rifle (or similar two-handed weapon), your accuracy in V.A.T.S. is significantly increased. This perk increases your chance to hit by 25%. As with all perks that increase your chance to hit in V.A.T.S., this bonus is multiplicative, not additive.

Bugs
As of version 1.1.035, it has been proven on the PC that this perk is nonfunctional, similarly to Sniper, Gunslinger, and Wired Reflexes. It has not been fixed in 1.4.06, and it is not known if the X360 and PS3 versions are affected due to the lack of any controllable means to test.
