So after torturing my mind about this I turn to you guys. I'm trying to figure out the purpose of the number 72 part of the crisis suit kit. I get the feeling I figured it out before, but for the life of me I can't remember. I've thoroughly searched the book trice, looked on the internet and used all logic I could muster, to no avail. I'll fully accept eternal shame on this.
Since part 71 is a groin pad, and 73+ support systems, I always assumed the 72 was an alternate and small groin pad too: it have the profile of the groin low and the carving for the "ball on the groin"
But since it is very small, I think that maybe this part seems to be mounted between part 71 and the groin to fill the gap (the assembly instruction of 71+72 seems to have vanished in the manual)
That might be it Kael'yn, thanks! I already assembled the groin plate (71) and I can't find a picture of the backside of it online so I can't confirm. However, I assembled mine without any problems and the part would be hidden, so I don't really understand the purpose if it is indeed used like this.
