I see SF as a combination of science expedition, police force, firefighters, disaster relief group, defense force, and diplomatic corps all in one organization.Of course it is. It's an armed service operated by a federal government and serving as the defense force of its nation. It has military ranks, structure, and discipline, and military institutions such as courts-martial. War is not its primary mission, but neither is it the primary mission of the US Coast Guard or the Japan Self Defense Force, and those are still militaries.
