In addition to Grognak The Barbarian, Unstoppables, and Awesomely Astounding Tales magazines, there is also a U.S. Covert Operations Manual that you have to collect in Fallout 4 if you wish to get useful perks for your character.
There are a total of 10 manuals scattered throughout Commonwealth. Just like other magazines that I previously mentioned, getting them will grant your character unique perks that make them more competent in battle.
If you would like to get all 10 Manuals, here are their locations:
