Well there goes the last item of kit that had been constant since 1991.
In 2003 I stood guard in Bosnia and counted all the kit that had changed from 1991 in the Gulf. From socks and boots, underwear and helmet, CADPAT and Goretex, Thermold to steel mags, C7 to C7A1, everything I was carrying or wearing had changed at least once - except for the bayonette and green canteen.
In 2008 I put on my gear in Afghanistan and did the same head to toe inventory. Over six years most of the kit had changed too. Although I wasn't issued a bayonette, it would have been the old standby. The next rotation had the German bayonette on their vests. So long old friend, but when a grunt needs to cut wire, he shouldn't have to carry another tool to do it.
(But my little Wonder Woman talisman hasn't failed me yet. She with me around under my helmet cover.)
