Yep! And the younger generation says we are wrong called them "clips"! LOL!My Granddad, dad, and uncles are all vets, they all called magazines clips. Especially in the Army old lingo dies hard. By the time my generation came around, "mag" was the accepted term. But, in many other cases, equipment and programs get called by the name of the thing it replaced. Troops that have never seen a deuce and a half call the 10 ton dump currently in service "deuce and a half".
You'll still hear "Strac" even though that went away in the early '60s. https://en.m.wikipedia.org/wiki/Strategic_Army_Corps
