One of the great things about anime is that it has subgenres which simply don't appear in any other kind of media. American pop culture is filled with war movies, and some of those movies even have attractive female soldiers - but there's nothing that really compares to the military moe genre, which takes exceptionally cute girls and gives them guns, tanks, fighter jets, and more.
Most of these anime about military girls are light-hearted and cute series that focus less on the gritty trauma of realistic warfare and more on giving the female characters a chance to be adorable in unconventional ways. There are a few exceptions that are darker in tone, like Gunslinger Girl, but by and large, the genre is a cheerful and positive one.
