It's just a strange way to do things... I know the Army is not the USMC, but the entire ethos with the USMC as it relates to Boot Camp is it is this transformational right of passage. If I had to do it again with the Army to fly, so be it, but I would think, even more-so on the prior service Army side, it would be almost an insult to be, say, a prior service Sergeant or even Drill Sergeant with years in going through basic again -- all based off what, your years since IRR drop?
I get wanting to refresh people, or send those from other services (heck, maybe even Marines, NSW, AFSOC, etc) through, but really it seems like not only a waste of time and resources, but somewhat contrary to the indoctrination aspect of basic training to be sending experienced soldiers back through. I'm sure a 2-3 week class and some DL could cover everything they feel they need to cover. Hell, I haven't done any drill and ceremony since I graduated boot in 2008, you bet your ass I'll be in my backyard with youtube on practicing that stupidity before WOCS. I don't need to be treated like a child for 10+ weeks to get that down, and neither should prior service members from the Army and certain other military communities.
Maybe only the USMC views it that way -- we would look at something like that as sacrilegious, even though from all I hear Benning is pretty much at a similar difficulty level.
