Oh, its real alright. If they made the training even slightly more rigorous the Shmoes would quit in droves. Therefore they made the training about as "tough" as an elementary school recess period.
From the videos I’ve seen of the PF in action, none of their rank look as pathetic as those portrayed in this video, even to just their physical stature.
It just doesn’t smell right. Almost as if too good to be true. Too aligned with what we woud LIKE to believe. I remain sceptical.
