I had heard of the RPG (rocket propelled grenade), the Russian version of America’s recoilless rifle. Basically it was a small rocket fired from a shoulder mount. The rocket body, about two inches in diameter, had a warhead about four inches. Because the weapon delivered more than two pounds of explosives to any target under two hundred yards away, it had a lot of punch.  My first RPG experience came right after the mortars stopped landing in places more distant from my hooch, and small gouging into the earth meant to serve as my foxhole. No self-respecting fox would have considered the mud pit, however.
