If a name change improves logistical support, then don't you suppose that there was something else wrong?
My point is that the Army gratuitously changes names for no apparent reason or benefit.
It's a new concept with an improvement to the existing infrastructure. They could call it the Fuzzy Lovey Bunny Brigade and it would still be a substantive improvement. Who cares about a name anyway?
As I mentioned before, the military, not just the Army, adapts to the threat, and in doing so re-organizes and re-names on occasion. Some Army G8 staff guy pitches a "new" organizational name to his boss so the Chief of Staff can pitch the "new" organization to DoD and Congress and the name and acronym grows legs. Next year it may be called something completely different to distinguish it from the prototype moniker. This process is not unusual nor unique.
Stand alone regiments and brigades have been organized and deployed in the U.S. Army numerous times over the course of its history (RCTs and Seperate Brigades for example). The names aren't necessarily what's important, it's how they're organized to fight and how effective they are that counts. You don't have to like the process, or even agree with why they do it, but there it is.
