Ah well, I decided that I didn't want his costume to suffer any damage, merely the bloodstains, much like Superman's costume (though not his cape) is protected by his invulnerability 'aura'. My thoughts were that BA would have gone rampaging through the closest large population center.
Composition is good, but there's one little factual error - the Israeli population in the Gaza strip is much smaller than 1500, as the IDF evicted all Israelis from the strip about 2 years ago, as part of an agreement with Egypt and the Palestinians. He would actually have had to go hunting for Israelis to kill, in which case his costume should probably be riddled with bullet holes and burns from all the fire he'd have taken.
