Ok, so I'm considering Aviation Ordnance or Ordnance because I was thinking about becoming a gunsmith after I was out of the USMC. Would this be a good way to go for my career choice? Any Ordnance guys input would be great.
03 is clearly the person to discuss this with. My opinion is, however, that you're jumping the gun.
And if your recruiter either cannot or will not answer these questions for you, they should be scrubbing toilets instead of recruiting.
