Mostly, Shermans at Saunders. An MGuP AU.

"What Sargeant Carm, i only know Corporal Carm."
Meet Carm in an alternate universe, were he ends up at Saunders with a friend named Sargeant Kasper. Watch how they dominate the rank of Sensha-do or "Tankery" as they call it over in the USA. 5 men against Japan, with discrimination, angry girls, modelmaking and bunch of Sabaton. From angry German wehraboos coping to the ears suffering from shell bounces.
