I served on active duty in the U.S. Air Force from 2001 to 2009 as a 2W0 Munitions Systems specialist and a C-130 Loadmaster. I served in the Air Force, not the Army, so this page is built from O*NET and BLS data rather than my own memories. The problem is the same in every branch: your experience is valuable, and it has to be written in the civilian employer's language.
