Normally, I am using "this and ! alive unitname" to check if a soldier isn't alive anymore, but now I noticed that this doesn't really work with Iron Front tanks- as a tank is only dead if he totally exploded (which doesn't happen that often in IF). My question is, what else should I use to see if a tank is inoperable? I.e. crew exit or is dead or the tank can't fire anymore, etc. Anyone can help me with that?
