"The M97 was a decent machine now. Long ago, it had some issues, but was really a prototype back then. Now that it has been around for a bit, the Scorpion has come onto its own. While the protection and mobility was good, it wasn't anything really special. But the gun is a different issue entirely. It is simply superior to the Paternian 120mm cannon in accuracy and penetrative power. At its very least, I suggest the Paternian Army jam this gun into any tank that can fit it.

(1) activates turret. (2) activates rooftop MG. (4) fires the main gun. Pitch and roll to control the gun. VTOL and Trim to control tracks. The Unity-PDI M97A6E2 (120) Scorpion III is a modernization program to the Unity Defense Corporation M97A6E2 (120) Scorpion III done with cooperation from Paternian Defense Industries. PDI was tasked by Unity to modernize the tank.

With upgrades to the armor, firepower, visibility, internal systems, drive system, and suspension, it is perhaps one of the most underrated tanks in the world. The Paternian Army found the machine to be highly proficient, comparable to current Paternian tanks. It's 120mm gun is a superior weapon to the Paternian system, and has been adopted into service as the 120mm Gun M9.
