Good point , in real wars it's not rare to see some old designs still being used in fights and even more modern ways to defend equipment and men are often failing to do so because of the shear power modern weapons have ( that's also why active defence syst are prefferred ) . I meant AMAP instead of AMAS , wrong letter sorry XD , if you don't know what it is it's a modular composite armor designed to being able to be added "on the fly" to counter specific treats . EDIT : for on the fly i mean from mission to mission , don't think that it could be added between engagements , it still need time to be welded or mounted on the vehicle
