You may have heard of kung fu, but the girls at Oarai High School practice gun-fu—really, really BIG 75mm gun-fu, in fact. It's called Sensha-do, and it's the martial art of operating armored tanks! They take it seriously too, and since winning the national Sensha-do championship is such a huge deal at Oarai, they sometimes go to extreme ends in order to get the best students from Panzer class to sign up. Which is how Miho Nishizumi, who HATES operating tanks, gets drafted to join doomsday-driven driver Mako, even-triggered gunner Hana, highly receptive radio operator Saori and combustible tank-fangirl and loader Yukari as the incomparable Anko Team. They may not be on the half-track to fame and fortune, and maybe a few of them would rather shop for tank tops than become tops in tanks, but once their focus is locked and loaded, they're absolutely driven.

When the Ministry of Education goes back on its promise to keep Ooarai Girls Academy open, the task of saving the five-mile-long Academy Ship from the wreckers falls to Miho and her barely-seasoned tankery team. However, things go off track almost immediately. While the Oorai tank crew may have won the high school tournament, they’re now facing a larger and more experienced university team, and if they fail, their armored vehicles will be forfeit! Will they be swapping their tanks for the memories? It’s possible, but winning a tank battle is all about tactics and teamwork, and the fledgling Ooarai students have more friends and allies than anyone suspects.

The main story retold from Saori Takebe's point of view.

“A piece of spaghetti or a military unit,” George S. Patton famously said, “can only be led from the front end.” However, once the heat of battle has cooled and the fog of war turns as thick as minestrone, determining which end was front and who pulled on what can be difficult. Therefore, for the enthusiasts who’ve puzzled over the epic tank battle between the girls of Oorai Girls’ Academy and their Italian-themed rivals from Anzio High School, we present these classified videos for your eyes-only! Miho and Team Oorai will have their hands full with the impulsive attacks of Vice-Commander Pepperoni and facing the raw fury of Vice-Commander Carpaccio… but the real question is whether they can hold off Anchovy’s ultra-secret secret weapons! Will they persevere? Or will their opponents end up saying “tank” you very much…

4-koma of the lives of the Girls und Panzer cast.

Tankathlon is a new form of tank sport gaining slowly gaining popularity among Senshado enthusiasts. While also involving tank battles, Tankathlon is distinguished by its lack of official oversight allowing any school with tanks to participate in a battle anywhere at any time, and a 10-ton weight restriction on tanks used, limiting battles to light tanks and tankettes.
