It kind of was. Although the fact that Snow was part of some silly little paramilitary group would make some of kind of training obvious, Snow and NORA have been fighting monsters in Cocoon.If there was an explanation it was probably buried deep in the datalog or some Ultimania cash-grab, because I can't remember one in the game.
I think it was also mentioned in its expanded universe.Functioning as a neighborhood watch of sorts, NORA members patrol the vicinity of Bodhum for trouble. Most often, "trouble" consists of encroachment by dangerous forms of wildlife.
NORA had never openly acted out against the Sanctum prior to the Purge, and because of this, the military had been content to turn a blind eye to the group's activities.
His weapon is also the same technology as Lightning's snap/Psicom's general manadrives thingies, it doesn't comes from fists it comes from the runes on his coat. That's why whenever you change weapons, his gloves don't change, it's the design on the back of his coat. Hope's description of his initial weapon tells us that it's a hunting boomerang, it's a stretch but it's not impossible to think that his family let him hunt I guess.
I'm not really here to rain on anybody's parade. Enjoy your snark, it's fine- I just have a knee jerk reaction to some of the nitpicky details I guess. There's lots of things wrong with XIII, but I don't need to suspend my disbelief on how some final fantasy characters got weapons/became warriors. In general, the whole twitter versus Spoony thing really soured my enjoyment of his stuff, though he did give a good apology afterwards, I just eh.
