You’re right that’s where you can practice firearms. Probably crossbows too. I can show you how to use one and reload while we’re here. [He’s not the best shot but he’s not bad at it either. His guard is still up. There could be monitors around but after a few floors not seeing any his shoulders stop being so tense.]

But defending against them is easier to learn. Someone pulls a gun you want to be behind cover or diving out of the way as soon as possible. At close range the shot is too fast to dodge.
