Many are totally ga-ga, of course, goes without saying, PTSD and PMS and all that and when they bend over to tie their shoelaces sometimes gin leaks out both ears but definitely better trained after a more rigorous selection process.
This is based on personal experience? What is your sample size and what does many quantify to?
The ones (4 UK, 1 US) I have met are remarkably sound individuals who don't conform to ridiculous Hollywood caricatures. IMHO the training is not the main differentiator, it's
selection both at the beginning of and during service.
