because my experience tells me that they are not SSGN, they might be sailors but thats it, their demeanour doesnt reflect any special training . they are just there for the show hence the ill fitting gear and unconvincing body language. those over sized gloves look more appropriate for baking and Barbecue manoeuvres.
the guy in picture number 8 is a different story. he is as legit as one can get. everything in that still gives of elegance, control and power. a childhood friend of mine is an SSG veteran and a senior instructor so I know few things up close.
