I can explain that for you dear knowledge seeker! After the fall of the 2nd REICH the Germans felt there defeat, and saw what happend to the extremists afterwords. So they Saved their own asses SS or not SS that didn't matter at the end it was lost so no reason to die for anymore, but more reason to try survive as much as possible...as at that point Germans weren't the fav pets, people gladly helped out after what they did...So they acted like a real soldier would react: They joined another promising cause and if there is one thing you can say about the SS, is that they were scary motherfuckers, in those days for sure! I am convinced that the strict lifestyle of most legionnaires still  has a lot to do with the after war in 1945 and the occupation and of course old habits that start to integrate in the ranks of most legionnaires, and start to be a part of their lifestyle! something you still experience in many ways. here few examples...Loads of ex SS songs are sung till the day of today!! Words are integrated in the sentences ex: Achtung or kamerad or if they drunk they say: je vais Steife ma geule. In your selection period you even have to pass The Gestapo and tell them every little detail from birth till intervieuw it's insane the feeling of  intimidation that passes your body at that moment hehe looking back at all this just makes me miss it again  '((Best time of ma life!!)  This are only few of the many habits that integrated in this exclusive club of nutcases that have a passion for war craft ;) cause if you decide to give everything up to start new, and you know how they work... you can not  be a normal person, otherwise you'd crack in no time, and believe you me bin there done that seen many crack mentally! To come out in tact you need few screws loose already in my eyes... (not in a bad way ofc!)Anyway a better training program still needs to be invented i think take the knowledge and know how to, or not to. is Deadly as no other cause you see the perspective of the to be used tactic from 156 different views and methods how to do your job in the best way there possibly is. For me this is crystal clear bounded knowledge find's a way in no matter how big the canal is! 
 That's about it for now i guess i could go on for houres and houres but i think i cleared some stuff or atleast gave a fun read to know from the experience of a Veteran
