All this talk about frag grenades reminds me of the time during my military days when, one day, we got an anonymous call that someone had taken a grenade out of a case, pulled the pin and put the grenade back in the cardboard sleeve and placed it back in the wooden crate. The CWO3, Chief Warrant Officer, that I reported to and I went out to the location were we stored a three day supply of ammunition to supply one Battle Group in the event we were called up.. I was in the 101st Airborne at that time which consisted of five Battle Groups and a Support Group. The Warrant Officer pried the lid off the first case we came to, looked in and right away spotted the grenade without the pin. Don't know if the clown that did that was ever caught but never assumed anything after that.
