These were weapons that were based off of Chitauri tech, but were redesigned by humans to be weapons. Maybe a few heat up? But trust me. If they were pointed at someone's head, it would probably blow their faces off their skulls along with their hair. Not a good look.
Since some of the tech it was based off of might be familiar to you, is there any way of counteracting a blast from one of these things? Like a way to disrupt them that you know of?
