Are you sure "military power" is the best way to translate 武力? It seems to me that in this context, it's simply referring to a shipgirl's "power" in battle as embodied by her weapons and whatever metaphysical "force" that infuses both the shipgirl and said weapons that allows them to stand on more or less equal footing with the Abyssals, unlike regular warships and ordinary humans.
Let's get you accustomed to using those bodies.More than half a century has passed ever since our first encounter with our enemy, the Abyssal Ships.Help me! I'm going to have to take supplementary class at this rate!!In brief,It's your fault for sleeping in class!Well, then, let's speed up! One more round!We currently don't know anything about them.First thing first,Their base, their scale, their goal...No means no!!Don't force it to come out...You can't cram all of that power...Into such a small body of one single destroyer...But know when the time is right to draw out your strength...
