Would the mortar round exit the tube quick enough and be airborne before the explosion of the AT mine?I heard a story about a mortar baseplate that some American troops found outside a firebase in Vietnam. The cong would slip in every night with the tube, and drop a few rounds on the fire base and then leave the baseplate behind, to return the following night. The troops left the baseplate where they found it, with the addition of a large antitank mine underneath. I believe that particular problem went away.
actually I located the EOD guy who assigned to the CIA station in Saigon, he was responsible for for controlling al the Project Eldest Son items and the 308 Special devices. His description of the 82mm mortar was much the same as EODguy described, b ut he said there was a set back firing pin in the ones he Xrayed. Seems a case of modified mortars got into a pallet of good ones, so he had to xray each round individually. He is looking gtoruhg his old VN stuff to see if he can find any old documents on it.
