If it was able to penetrate a car body, it'd be a great asset for checkpoints and roadblocks — surely better than live-round warning shots. Do they have those anymore? It'll help in riots and other such things, I'm sure.
It sure is a nice, big target for insurgent RPGs though! I wonder in what ways it'll be protected — even mounted on a heavily armoured vehicle, the dish would be vulnerable to damage, right?
