I can't speak for the Army lately, but the entire Navy and Marine Corps seem Hell-bent on shoving 15lbs of shit into a 10lb-bag. It could be argued we've been doing this since at least ~2005....well, chickens are coming home to roost, the people who suffered in silence due to their post-9/11 motivation are at/near retirement age. Folks with <10 years service are looking at the insane workloads, the shit compensation, and are not sticking around.
