Eh the army brought Gracie's back in 2009 at fort Jackson and the Gracie's tried showing us how 'effective' bjj was no matter how big your opponent was.. well one staff Srgt volunteered .. he was 5'6 200 lbs ripped and on the juice .. well they started with the Gracie on the bottom, caught him in a arm bar and the Srgt ( while chewing dip) lifted him up with one arm and slammed him on the ground and took side control lol .. they tried again with a bigger Gracie so another staff Srgt volunteered .. he was 6'5 250 lb red neck .. started on the ground then he got caught in a triangle ... the Srgt ended up pretty much powerbombing him lol .. after being humbled a bit= they went on with their lesson and it was a good one I will say .. but the army decided it wasn't worth investing much in it..
