if you look closely, near the end of the film, one of the soldiers takes a good hard kick at the groin of one of the youths.
this, imo, is just outrageous. infertility could come of that, and then you've got another willing suicide bomber in the making.
the other bit that was out of order was the 'headbutt' (more like helmet butt) right near the begining. that was sick.
