I remember one candidate tried calling them that at OCS. He received a firm "What the f#@!* you think this is candidate...the Air Force!?!?" We stuck to utilities and cammies from that point on. So, I can't speak of what they were referred to as, but we were "discouraged" from calling them that name at OCS.
Oh and we had the chance to ask a Captain why the digital pattern for the new field uniforms. He said that they were designed with small and large shapes, rendered as blocky, edgy designs. This variety of size and sharp edges forces the eye to soften the actual appearance of the uniform because the eye has a tendency towards soft edges. So just looking at the sharpness and variety causes the eye to blur it moreso than just looking at a soft shape, as with the older uniforms. Plus, Marines always have the most kick a55, latest and greatest uniforms. Maybe not the rest of their gear, (we were using Alice Packs, literally from the Vietnam era during OCS) but Marines will always be looking sharp. But alas, the other services are slowly introducing their new MARPATS as well. The Army is forefront among them, but an airman in digital blue/white cammies just looks "off" to me.
Ah, found a pic, guess it's not digital, just fat-man Hawaiian T-shirt themed:
Sorry to thread jack, I'm easily distracted.
