U.S. Covert Operations Manual (Fallout 4)

U.S. Covert Operations Manual is a perk magazine in Fallout 4 that gives the player character ranks of the Covert Operations perk.

Background
U.S. Covert Operations Manual is a training handbook produced by the United States Department of the Army to train its personnel in the art of subterfuge. The manuals were not intended for public circulation and were marked "Authorized Eyes Only."

Characteristics
Each magazine gives a rank of the Covert Operations perk which makes one more difficult to detect while sneaking.

Magazine issues
* Note that the graphics of #7 and #8 are reversed (see bugs), so if you check your inventory for which ones you have and which not, reverse those two.

Behind the scenes

 * The collection of manuals is based on real world Field Manuals issued by the US Department of the Army, particularly those issued in the 1960s.
 * Some of the issue titles also refer to common phrases and to real world pop culture:
 * "Whistling in the Dark" is a common idiom meaning "to put on a brave front."
 * "Not the Soldiers You're Looking For" is a reference to Star Wars Episode IV: A New Hope, where Obi-Wan Kenobi says "These aren't the droids you're looking for."
 * "Who Goes There?" is the name of a science fiction novella by John W. Campbell, Jr., written in 1938 and made into several films, the best known of which is John Carpenter's The Thing (1982).
 * "Squeaky Floorboard, Sudden Death" is a Splinter Cell reference, in particular to the third game in the series, Splinter Cell: Chaos Theory.
 * "Bushes, Boxes and Beehives Camouflage Special" is a nod to the Metal Gear Solid game series, of which hiding in a cardboard box is a signature, and where Snake may hide behind bushes, under boxes and use beehives as a method of distraction.
 * "Look Better in Black" alludes to a quote from City of Bones, part of the Mortal Instruments series of novels. The quote is as follows: "It means 'Shadowhunters: Looking Better in Black Than the Widows of our Enemies Since 1234'."
 * "Tiptoe Through the Tulips" is a reference to the song of the same name.

Bugs
The world graphic of issue #7 matches the inventory graphic of #8 and vice versa.
