Done on the fly. But here a story I've cook while I upload.

"Arca base is know for its long range artillery but also know for having a massive weakness: Low fire rate and inexistent short range defence. To fix this problem, the Arca corporation came with the I-TR 75 (called Intelligent Trench tank) as mobile turrets all around the base. It use two AI (Driver & gunner) and can communicate with other tanks to tighten and reorganize the defence belt when a I-TR would come to be destroy. The "Box" is equipped with all kind of electronics warfare and the tank can be park in very deep trench or under water if needed.

In addition of that, they deployed drones to support the tanks and the artillery for better accuracy."
