Hey I didn't make the term... "CAC card" was basically how 99% of everyone referred to them. They probably still do. But I think the reason we did was because "CAC" as a stand alone term is awfully close to another word that would be highly unprofessional don't you think? It's one of those things you think about in basic training after they issue you the card for about 30 seconds before you stop questioning shit because they're screaming at your face (which I hear has changed a few years ago...). So maybe they have more like 5 minutes to think about these days.
