Happens often I hear.
But there are other means, too. A pal of mine tasked with being part of an *insurgent mortar team* during one CITA predeployment field exercise deployed with his favourite [lightest] 60mm M224 mortar and set the thing up, after which he dropped a 3-foot long section of black spraypainted 4-inch waterpipe over the top half of the tube. Whereupon, the scout platoon who was supposed to find them reported the position as a 4.2"/120mm position, and accordingly had all their friendlies keep their vehicles out of the 7200 meter range of the bigger feller. Yet when the mortar team packed up in their Toyota pickup and redeployed, they were up and gone in less than half a minute.
His new term for a buck's worth of scrap PVC pipe is a *VisMod Enhancement Device.* And given time, I bet he comes up with other little surprises
Sounds better than getting stuck in the middle of the guys playing OpFor and driving out with one of their vehicles.
