Right, but the body armour is probably equally important or more so than the gun. After all, crazy dude just starts shooting and yer first the gun don't mean much. The body armour buys you the time, hopefully, if shot to actually return fire.
The gun is critical, surviving to use it? I'd say just as much if not more so.
Of course, I don't have body armour so I'm hopeless... but I do think about it.

If the guy shoots you first... you're probably dead anyway
Yup, armor saved my buddy's life. BG got the drop on him (action beats reaction) and Greg took one to the gut. The armor allowed him to return fire and kill the BG.
