Minutemen General's Uniform

The Minutemen General's uniform is a outfit that can be worn and obtained in Fallout 4. It is the traditional armour of the Minutemen General, and as such is styled as a Revolutionary-era uniform.

Characteristics
It provides a Damage Resistance of 40 and an Energy Resistance of 80 which gives it a total damage resistance of 120 as well as a bonus of +1 Charisma and another +1 charisma if coupled with the unique Minutemen general's hat (also found on McGann's body).
 * Due to its high stats and low weight, as well as the bonus charisma, it is ideal for a Sole Survivor that specializes in wearing protective armor at all times to give them reasonable protection and a bonus for speech checks during quests and jobs.

NOTE that you cannot wear additional pieces of armour under the Minutemen general's uniform as it is a whole suit of armour.

Locations
Found on the corpse of McGann in The Castle tunnels which leads to the Castle Armoury, which only becomes accessible during and after the Minutemen quest Old Guns.
