Not quite. The clothing that a Marine wears is thicker than other clothing, which will be extra padding, and there are knee and elbow pads to allow for jumping to the ground with minimal discomfort. Minimal as in next to none, besides the jarring from jumping to the ground. My brother once spoke to a Marine on leave, who did indeed say "you don't even feel anything,' and with the modern camo, he would say that he could lie down on green grass with green fatigues and would disappear. Supposedly, so says the Marine.
