So drive a vet 1 soviet tank on the point in capture mode, or drive any USF vehicle and hop out on it.
On "Close the Pocket", there is a big difference in actually getting a unit to decap a point as opposed to being able to neutralize a point on the far side of the map without needing sight on it for 80 munitions. But thats only somewhat annoying and doesnt really do damage.
I kind of already forgot the names of which is the neutralize point, and which is the "wipe map" button, but i think there should be at least a max number of sectors that can be artied' to death.
