re: Question for military folks.

It could be fired from a 105 mm recoilless rifle or presumably an armored assault vehicle gun tube or a tank. They were used when I was in Vietnam and I saw what the bazillions of little nail like flachettes (sp) looked like. (Inch long nails with tiny fins.) I think the original purpose was for use against massed troops in the open, but not sure. All I know is we had them, used them, and fortunately I never had to look at the end result.
