When I went through basic in 2011 it took a substantial amount of US dollars (I think 250,000 is what we were told) to put a soldier through basic training and ait. That just initial level training. I think food and housing alone for those couple of months is something like 44,000, but you have to figure in insurance and salaries and travel to and from (for both yourself and everybody training you) and all this other craziness to the fold as well. The numbers can be skewed because it cost less to train an infantryman than it does to train a tanker, and less to train a tanker than it does to train somebody who deals with nuclear weapons, etc.
Delta typically comes from the Ranger Regiment. Who have an intial entry course to get in, airborne school, and then Ranger School, and then many from there go to one of the Special Forces groups, which has its own initial entry selection process and training course which can be over a year long. To be in Delta there is another selection process, plus another six month long operator course afterwards.
Somewhere in all that you have military free fall courses, scuba diving courses, language courses etc. and each unit has their own in house training that never stops.
Literally YEARS of training to get to that level and if it cost 250,000 bucks to just get an initial entry soldier through training IMAGINE the investment the US Government is putting into each of those guys. There not going to want to put those guys in situations where they don't have the best possible chance to come out with the W,
I think it was Chuck Pfarrer who stated that the Navy's version of Delta which is ST6 shoot more in the peacetime military than the entirity of the Marine Corps did in the same period. A handful of guys who had to be so proficient with their firearms they outshot an entire BRANCH of the US Military.
The shit is fascinating. Everybody with even the teeniest interest in military should check out their countries military elite. Our guys have masters degrees, speak multiple languages, run human sources like intelligence agencies, are marathon running body builders, and function as human automated turrets who have to hit something ridiculous like 95% of the targets they shoot at in training to stay Delta/Devgru.
