The absolute gayest perk in all of Modern Warfare 2. Unlocked at level 4, this perk will allow someone on Xbox Live to lunge and knife someone on Playstation Network. Anyone using commando is virtually invincible to bullets and/or explosives. This perk is usually accompanied by the perks Marathon (unlimited sprint) and Lightweight (run faster) and a pistol with a tactical knife, so those little faggots can run 50 mph and knife someone every second.
