the most fun thing to do with the field gun is to have an advanced spotter sight in targets that are BVR from the gun. I was playing on fools road spotting for the gun on NE side of the map that looks down that road. The brits were setting up a TOW to defend the village. I spotted for the gun and we pinpointed the exact spot it would hit the TOW and just started blasting it constantly. Theres not much you can do when a gun is shooting at you from about 5-6 grids away lol
