I've tried equipping armor to an item slot, and then using it on a companion. I have also tried trading it to the companion, but that doesn't work either. So I was wonder if / how you can get a companion to wear armor.
Also, another question that doesn't really deserve it's own thread; where can I find the guard station in Junktown? I looked in the building right at the entrance, but Lars, the person I need to talk to so I can bring Gizmo to justice, wasn't there. The wiki solved that one.
