i did a 6 month tour with The Royal Gurkha Rifles as a SNCO as part of the deployment in Cambodia
we had a small group of 40-50 KR operating in the area and a call came in to take em out as they where firing on planes .
well they had this spot set up with a few bunker dug in around the peak of a pyramid shaped hill
no way up in daylight without being spotted and the 12.7 mm they had was rather accurate
come night though ..
come morning we had the 12.7 two mortars and a wombat recoiless that would have cut us to pieces if we'd had of tried a assault ( 105 mm canister and fletchette rounds )
and a few dozen personal weapons and a couple prisoners to tell the tale
good folks eh ..
