No, no kiddin'. IIRC, it happened during a live press conference with Chief Moose early last week. I'm about 98 % sure it was early last week. Anyhow, Moose was quit cool about it....while most everyone else was panicking.
He was the one to stand up to the mike and say, very authoritatively, "BACKFIRE", then finished the sentence he had begun before the interruption as though nothing had happened.
Neither a flak jacket nor a helmet (either kevlar Fritz type or the old steel pot) will stop a 5.56x45 round at any reasonable range. They are designed against shell fragments, (hence the name "flack" vest), which historicaly are the big killer on the battlefield.
