What kinds of certification or education is required for civilian quality assurance specialist (Ammunition)?

Sorry, when I read this, the first thing that came to mind was Bugs testing cannon rounds.

Go to safety.army.mil and look up the online training area. I tried to find it myself, but couldn't find the exact location. There are certifications that work for both military and civilian. Look up Ammo handling, Ammo Safety, Explosives Safety... I would also recommend finding the Ammo Warrant Officers on RP and hit them up for advise.

Defense Ammunition Center McAlester OK hires interns for the Civilian QASAS career. A degree is helpful since they were currently only accepting college level applicants. Check out the DAC web site.
