钻石城的保安都配备了铁管步枪和棒球棍，所穿的护甲都是战前的棒球防护装备，possibly looted from the baseball stadium the city was built inside.
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.
- 在任何情况下杀死一名钻石城保安都会使所有的保安敌对。在早期，由于他们generally have skull icons next to their health meters，代表十分具有威胁性。
- 暂时离开钻石城等待 24 小时之后再回来，钻石城保安就不会再处于敌对状态。
- 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.
- "Oh, man. You got a robot butler? I want a robot butler..."
- "Hey, you that trader, up from Quincy? You sell any ointment? I got me this itch..."
- "So it's true then? You're leading the Minutemen? Good for you. Great cause."
- "Park the car in the yard? How 'bout I hammer you in the heart with a haymaker?"
- "Yeah, It's true. I got shot in the ass last year. Long Story."
- "How come whenever something interesting happens around here, you're right in the center of it?"
- "What's with you Vault Dwellers and those jumpsuits, huh?"
- "The legend himself! Way to give it to The Institute. You're like my hero or something...I dunno. Thanks."
- "There he is! The man of the hour!"
- "You cause trouble, there's gonna be trouble, got it?"
- "You watch your step. Got my eye on you."
- "Broke up with my girl. She kept the cap off the toothpaste. Know who does that? A synth."
- "Hey, I heard what you did for ole' Travis. That was real nice of ya."
- "What? You got a staring problem?"
- "If you're hungry, you can grab a quick bite at Power Noodles. Just talk to the robot."
- "You keep looking at me like that, I'm gonna start thinking you're a synth..."
- "Hope you didn't run into any trouble getting here. That bridge across the river - Super Mutants use it as an ambush point."
- "Geez, pal. I like guns too. But you think you might be overcompensating there?"
- "No funny business around the Mayor, got it?"
- "You been to Goodneighbor? Friggin' hole. Ghouls and chem heads all over."
Diamond City security appears only in Fallout 4.
