On the ship I fly on, we kind of built our own vocabulary a bit. We use a variety of terms for the rebuildable armor, "Armor, hull armor, hull (even, though outsiders on our ship might be confused)" When it comes to perma, the two terms we use the most are perma and red, for the red hit markers. To shout that the enemy armor is down, "They're red!" is what will be used almost all the time, again for red hit markers. When we talk about the integrity of their actual perma hull, we use "perma". Sorry if it doesn't make sense xD It probably isn't conventional but it's what works for us currently!
