I recently join ASG and found your post. Though your psot may be almost two year old, I wanted to add some insight.
I'd been an 88N since 1984, when it was 71N, until my retirement in 2006. I served in both Reserves and Active capacities. The TMC is an excellent MOS which can take you around the world. Before my retirement, the Army had just opened the WO program for 88N.
I sevred as a Training NCO, Admin NCO, QA NCOIC, Special Operations Support Section Leader, Battle Staff NCO, Platoon Sergeant, acting First Sergeant, and AC/RC Liaison (Instructor/Writer for TRADOC).
During my reserve years, I served with the 313th Trans Battalion in Baltimore, MD (Curtis Bay). Having a boat company on hand for training, I was much further in my experiences when I went Active Duty. I also served in Germany at Rhein Main Air Base during the first Gulf War. So, being on a joint assisgnment with the Air Force was also a blast.
The 88N MOS has alot of applications for the civilian workforce. Travel Agent, Relocation Agent, Ship and Aircraft loading. UPS and Fed-EX uses 88Ns at many of their hubs along with manyof the trucking companies.
Just ensure that you take as many of the supplemental training at Fort Eustis like ADLP, UMOC, TC-AIMS II and TOPS.
Hope this helps you in your 88N career.
