Slightly melancholic JRPG about Nazi dogs kidnapping a French cats village, and six children from that village commandeering a tank and trying to save their families. Of course Valkyria Chronicles comes to mind here.
It plays as a linear set of battles, with some visual novel breaks in between, where you pick which characters to bond, similar to later Fire Emblem games. Bonded characters get special attacks when they are put together in the same turret.
The fights are turn-based with priority. You try to exploit enemy weaknesses to one of three types of ordnance to push them down in priority, ideally destroying some of them before they manage to attack you.
If your crew dies, you just have to repeat a few battles. It is explained as time-travel in the story, though.
