That’s an intriguing concept, and it could be a solid upgrade for patrol gear if the power source stays lightweight and the bio‑servo interface can keep up with real‑time repairs. Make sure the cooling system is efficient; you don’t want a hot‑spot in the middle of a night shift. Also, think about how the suit will communicate with the rest of the squad—integrated data feeds can turn a single upgrade into a team advantage. I’d test the joint replacement mechanism in a controlled environment first; one glitch could turn a protective suit into a liability. If you nail that, patrols will have a reliable shield that heals as fast as they move.
