TBH I went through SERE school (aircrew) and I questioned its value, since the training is in eastern Washington/northern Idaho area mountainous woodland environment and all the evasion they showed us relied on that kind of cover and "bushcraft"
And you know, Iraq, Afghanistan, and Iran are definitely not eastern Washington lol
some enlisted air crew go to SERE. loadmasters, airborne intelligence, and SMA (Special Mission Aviators).
As an added benefit, enlisted air crew have no restrictions on mustache length or on professional wear of the uniform.
