Ok, I understand now. So I'm guessing the jet pack attaches to the harness with clips or D-rings and hooks or something? BTW do you put the harness on first and then feed straps through the vest and back plate or does the harness go through the back plat from the outside so when you put it on you slip on the vest and stuff and fasten the harness then close up the flak vest? Also, this has nothing to do with the jetpack, but what do all the different Fett types mean? (eg) ROTJ, ESB, ect. I'm just wondering.
