Yes, without a doubt it is cheating. The comment by the marines about always cheating is out of context here. EMP would remove the ability to sight unless a measure was built into the gear to counter it. If the marines go into the field without that measure they can not cheat it into their mission. In video games the red dot hip shot device is not built into the game and the EMP is intentionally introduced as an aspect of game play. Besides, how would any marine cheat such a thing into his own hip shot? Your character and his aim point do not move. Everything around him moves...not so with the marine. Needless to say, many already understand this and attempt to hide their own use of it. The claim of elite is false for so many.
