Awesome post.
My job in the military is not an actual rigger, but I have 20 observed reserve repacks for a MC-6/T-11R (static line round) and MT-2XX (9 cell Ram-Air). I have been through a military riggers course and I have an military rigger certification/ qualification. I want to get my senior rigger qualification. Can I just do an observed 20 repacks on a modern sport rig and take the written test? Does anyone have experience with this? Thanks a lot for any info. For some reason nobody at work actually knows the answer.
