One episode had a girl in a skimpy bikini cleaning a tank and there were three or four episodes with open bathing. But all girls are shown in the water, no bare butts or boobage, even very little cleavage. More thrown in as a humor element rather than "fan service".

Very mild scenes of sexual content.

An episode contains some girls bathing in a hot tub, the nudity is covered by the water and their face and very small cleavages are shown.

Zero gore, no deaths, no one even injured except for scrapes and bruises. It's intended as a humorous rather than violent show.

This show is not very bloody in violence but it contains explosions by tanks. Tanks are shot and blow up in fire and lots of gunfire is heard. The show is like a battlefield but without any ogre, the kids will probably not have an issue with this.

Unofficial subtitles may contain much more explicit language than the official subtitles present on paid streaming sites and licensed discs.

Mild and infrequent cursing and some very mild dialogue.

"Damn", "hell" and "oh my god" is barely used during the series.

Very infrequent use of the word "ass".

One would be hard pressed to find "frightening" scenes in a humorous anime about high school girls involved in non-lethal tank battles. There is lots of intense action, but nothing even remotely frightening.
