Military!

One day while Souhei Yano is all alone a tank rams into his house. Inside is first lieutenant Lutgarnikov and second lieutenant Haruka from the Duchy of Krakozhia Army Special Forces. They have come to protect him from Assassins who are out to kill him. The reason being is that Souhei's father is hailed as a hero in the Duchy of Krakozhia. If something were to happen to his family it would give others a leg up in the war. While Haruka and Lutgarnikov have come to protect souhei, more often they tend to put him in danger, like firing missiles off in his house, and not paying attention when assassins show up. Will Souhei really be all right?

Military! is a fun anime. It has a wild sense of humor, which I really enjoyed. There is fan service here and there, but it's mostly panty shots. Though there are some revealing swimsuits in the beach episode. If you don't mind Ecchi anime, I would suggest giving it a try. Every episode is only three minutes long, so you can finish it pretty quick.
