Girls und Panzer: Little Army (ガールズ＆パンツァー リトルアーミー) is a spin-off manga from the original Girls und Panzer story, being a prequel from the main series. The story revolves around Miho and a few of her classmates during elementary school and their first contact with sensha-dō, which is exceptional, as elementary school girls don't officially practice it.
The story follows Miho Nishizumi, Emi Nakasuga, Hitomi Yuzumoto and Chihiro Yusa during their last year of elementary school. They already knew each other as classmates, but Hitomi's interest in sensha-dō made her and Chihiro approach Miho, as she was the sister of a former student of that school, Maho Nishizumi, who was already achieving victories in sensha-dō during her first year of junior high school, possibly at Kuromorimine Girls High School; while the trio approached Emi due to her historical acknowledgement on sensha-dōck in Germany, becoming close friends.
The four of them tried to make up a tank crew while passing through some ups and downs, with Miho considering quit sensha-dō because of the Nishizumi Style, Emi's selfishness, arrogance and lack of reciprocal interest to the group, and Hitomi's inability with sticking to things. Chihiro was the only one to not show any divergences, however she didn't show interest on sensha-dō as she only followed Hitomi, but she was a great support in ensuring that Hitomi wouldn't quit.
They managed to make up a one-tank team with a Panzer IV Ausf D with Miho as the commander, Emi as the driver, Hitomi as the gunner and Chihiro as the loader. They only had one mock battle against Maho's junior high school crew tank. This sensha-dō experience was short lived as elementary school was about to end and they needed to start making decisions regarding their future, Miho decides to continue practicing sensha-dō to find her true way of fighting, Emi decides to go back to Germany to do the same, Hitomi's fate isn't clear, but Little Army Two shows she stuck with sensha-dō and Chihiro takes on a non-sensha-dō path as seen in LA Two.
