What are the washout rates of all the special operations training programs?

Other than SEAL, I don't know about other units. SEAL is one rating in the Navy that have always been undermanned, so I have never heard or believe that BUDS candidates were purposely dropped. Though, I have heard of the whole cl that was dropped because no one could p it. And I agree with you that aside from physical stamina & endurance, you must have some brain & a lot of common sense to become an operator.
