Well, "to restore and maintain civilized order" the army [and the population it is drawn from] needs to be civilized first. As a thought experiment, imagine trying to do it with an army of barbarians. Thus, they will be ready when transcivilized [i.e. when they overcome their sectarianism ant tribalism, for starters], and not a millisecond sooner.
I take it you don't think they're quite ready...
