The green/winter, desert/summer thing was silly to start with.
Agreed. It does nothing for us, other than give some people an opportunity to send out painfully detailed instructions as to when one can wear each uniform on the day the turnover occurs. Pick a uniform and stick with it. (I've always been a fan of greens, whether they be Woodland or MARPAT, as green hides stains better!)
Rolled sleeves have always been distinctively Marine.
For the past 30+ years, it has. However, no nametapes was always distinctively Marine. Rank insignia on covers was always distinctively Marine. Campaign Covers were always distinctively Marine. Gaiters were always distinctively Marine. etc, etc, etc...
The sun will still rise on the 24th, and a new generation of Marines will be able to talk about the "Old Corps, back when we used to roll our sleeves."
