what evidence to you have to say otherwise?
i taken into account the lack of acclimation which would not be granted... heats, clothing, combat gear, boots.. about 3 to 5 miles running at a steady incline. plus, the added weight that they put on for their training would effect them adversely in the situation due to impact on the knees and ankles.
plus, i seen the muscle bound idiot marines fail consistently due to their stupid MMA training mostly due to added weight hell some are mostly muscle that they are unable to cross a pool in gear.
its just different training styles we trained overall not one specific attribute of size and muscle.
also there is a certain unspoken standard of whic marines can do mcmap from rank, belt colr to fitness and on top of that there a large drop off due to set standards.
most marines train to prep themselves up so as not to get kicked from training prior to voluntaring.
