U.S. Covert Operations Manual

The U.S. Covert Operations Manual is a magazine in Fallout 4.

Characteristics
Produced and issued by the Department of the Army to train its soldiers in the art of subterfuge, there are ten issues in total of the covert operations manuals and each issue found adds a rank to the Covert Operations perk, which slightly reduces the chances of being detected while sneaking.

Behind the scenes
The title of issue 4 "Not the Soldiers You're Looking For" is a cultural reference to Star Wars.
