But with that kind of system, the shooter will not have the luxury to shot a second one... it take out sniper that break your sensors and equipments with heavy rifles. It's way better than to find them visually.If you turn the corner into an RPG 20m away in a building, even if you locate the shooter its probably too late. I don't see how it solves the fundamental issue of tanks being big and loud and infantry always having the first shot.
Main battle tank are still made to destroy other tanks, it's why they bring support vehicule with them usually. But having that kind of system help a lot.
