One thing I've noticed in the fallout series, enemy AI (raiders, gunners, super mutant, etc) seem to be protected from collateral damage from their own explosives. On more than one occasion I've seen a raider or super mutant throw a grenade or cocktail only to have it explode near them because of some obstruction that was in the way. When I looked at their health bar, no health was lost. I know for a fact that they was well within the blast radius of their explosive. Another time, I rushed a raider with a machete while using PA, he was armed with a rocket launcher and shot me, I lost a little health, but he didn't lose any and I was within 2 feet of him. It is not coincidental, I feel the enemy AI is protected, but I could be wrong. Your thoughts?
