Sounds like you should be an armeror. They fix and modify guns of all shapes and sizes. Or, you can be a grunt and work your way to a weapons expert. They are more experts on the operations/use of weapons but certainly know how to work on a firearm as well.

I have a unique job (not here at recruiting commands) and I have worked closely with just about every job field in all the services. Not all specialties but I have knowledge of all the general fields. So, feel free to call me and pick my brain or email if you are more comfortable with that or we can just talk here.

As for which service... You know my answer. But, I have lived on Arm, Air Force, Navy and Marine bases, so I can tell you about the differences in life styles to.
