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
In the 1.1.035 patch, perks affecting the to-hit chance in VATS are nonfunctional. Thus, Commando is effectively useless until this bug is fixed.
