that's true for the original, but should it really be that way?

IMHO, unconscious soldiers taking no damage from fire is a design flaw, and should be corrected... they should also be able to receive stun damage, and explosions shouldn't affect them as items, but as soldiers/aliens.
heavily armored guy falls unconscious from a stun bomb, simple grenade goes off and completely wipes him off the face of the earth (or mars, for that matter

)?
seriously?
