Commando

Commando is a Fallout 3, Fallout: New Vegas and Fallout 4 perk.

Effects
In Fallout 3 and Fallout: New Vegas, the perk increases your chance to hit in V.A.T.S. by 25%. This bonus is multiplicative, not additive.

Effects
Ranks 2 and 3 each add 10% hip-fire accuracy, for +20% total. Rank 4 gives a 4% chance to stagger a target. Rank 5 increases this to a 6% chance. In addition, if Nuka-World is installed, Commando now becomes a crafting perk, mainly for the automatic variant of the handmade rifle.

Affected weapons in Fallout 4

 * 10mm auto pistol

In general, Commando affects any automatic pistol or automatic rifle, but, despite its wording, does not affect automatic heavy weapons. There are also exceptions - for example, a pistol-gripped plasma thrower is automatic, but is affected by Gunslinger, not Commando.
