Unless the US military is stupid to keep all 100 of them in a single easily bombable location, there's no fucking way on this green earth a single one of them will die in any combat, especially if they are simply manning air defense outposts spread across the country like what the article that no one here reads actually said.
Anti missile and aircraft systems are obviously the #1 targets in any attack. And the Israelis gain much more by letting them get hit than by making sure those units are protected in any way. They might even secretly shoot at them themselves to speed things up. I would not want to be one of those THAAD operators.
