I suggest placing the RM under "friendly" rather than "allied" since our mandates are different. Saying both factions are allied suggests that they work towards the same goals (only in a very simplistic analysis that is so) and execute similar activities (not supposed to be doing that). In fact, it wouldn't be bad RP to have policemen and militarymen slightly disliking each other, since they would, from time to time, step on each other's toes.
Also, at least in my opinion, "allied" isn't a greater level of "friendliness", but something different. The change wouldn't necessarily mean the factions would have to be less "friendly" towards each other.
