Well, guess it wouldn't be THAT extreme. Only difference, my BIL does it with full combat gear and actually drops into LZ's this way. But here's a pic of Kyle doing a HALO jump. He's in the Special Forces, and is currently an instructor at HALO school down in Arizona while away from his unit here at Ft Lewis.
Mind you, he's not wearing any special gear accept his Full oxygen mask (for the super high altitude). But he's just in his ACU's.
