Military Animes?

Hey buddies!!! Does anyone know if there are any military animes? I can't seem to find any besides the Wolf Brigade movie. I'm looking for something beliveble. Nothing crazy with robots gundams or characters who can jump over 50 feet in the air and do crazy combos. Can anybody help this poor sap?
