Commando

Commando is a perk in Fallout 3, Fallout: New Vegas, Fallout 4, Fallout 76 and Fallout 2d20.

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
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.

Modifies weapons
Commando affects all automatic rifles and their unique variants. For weapons that are pistols in their basic state, a rifle stock/grip must be attached. See Expert Commando, Master Commando, and Gunslinger for more information.

Fallout 2d20
When making a ranged attack with any weapon with a Fire Rate of 3 or higher (except heavy weapons), add +1d6 per rank to the weapon’s damage.

Weapon mods that increase fire rate can make them affected by Commando.

The level requirement increases by 3 after rank 1.
