Sending a shotgunner against a rifleman with a rifle that goes brrrt is not good.
A good friend of mine served in Vietnam in an armored unit. Shortly after arriving in country he was assigned to an infantry outfit as a liaison officer. He being a country boy from South Georgia that grew up bird hunting swapped his M16icon for a Winchester Model 12 trenchie and carried it for the rest of his tour. According to him, it worked quite well against little guys in black pajammies firing rifles that went brrrt.
