Diamond City security is the main security force of Diamond City in 2287.


The Diamond City security force was established to enforce the law and protect the city's residents from local raider gangs, super mutants, Gunners, and other dangers. They are friendly towards the Sole Survivor unless attacked first.

The Diamond City security guards are armed with customized baseball bats and handmade automatic pipe rifles, and are equipped with old pre-War baseball gear as armor.[Non-canon 1]

Interactions with the player character

The Diamond City guards will engage in combat nearby, even if in that zone. The guards will only attack hostiles unless the Sole Survivor aggravates them. They often share insightful commentary on areas, potential quests, and events that have occurred in the Commonwealth.


  • Killing a Diamond City guard will turn all guards hostile. They are a rather powerful opponent as they generally have skull icons next to their health meters early on in the game.
  • Outside of Diamond City to the left, there is a terminal towards the baseball statue where the turrets may be deactivated. These turrets will respawn or reset to their activated state after a few days.
  • Leaving Diamond City for 24 hours or longer will reset all hostile guards in the city.
  • Except for X6-88, Strong, Dogmeat and Ada, all companions dislike killing guards.
  • All guards are male.
  • Diamond City guards will mention the Sole Survivor's comments for the last part of the interview with Piper as one of their passing comments.
  • Diamond City guards share the same face model.

Diamond City security appears only in Fallout 4.




  1. Fallout 4 Vault Dweller's Survival Guide p. 34: "Diamond City Security
    Diamond City Security is responsible for keeping hostiles out of the city and maintaining order within its walls. Law-abiding visitors and residents have nothing to fear from Diamond City Security, but infractions like theft and violence are generally met with overwhelming force. For the most part, Diamond City Security uses repurposed baseball equipment to keep the peace. Their standard-issue armor favors damage resistance over energy resistance, and all guards carry some sort of baseball bat. Each guard also carries a pipe rifle and at least one stimpak, relying on superior numbers and emergency healing to overwhelm better-equipped enemies. Luckily, it's fairly easy to prevent confrontations with Diamond City Security—avoid committing criminal acts (or make sure such acts go unwitnessed) to ensure that these guards leave you in peace."
