I just noticed the OST cover for Wild ARMs 2 says, "An Awkward Rush & Mission Savers." Is that what ARMs stands for? In the original it was Ancient Relic Mechanism, referring to what we would call "guns." In that world, they were an old technology recently rediscovered and was causing alarm in the general population. ARMs in the second game was the name of the group saving the world, but they never explained the acronym. If it is indeed Awkward Rush & Mission Savers, then I understand why no one felt it important to mention it.
