I'd say, Rob, that with your experience, professionalism, knowledge of the tools of the trade, and tactical and technical proficiency, you've earned the right to be addressed as
Sergeant, or at least "ATJ"--(actin' Texas Jack)

A former president of the Republic of Texas started out as a corporal in the Texas Army. Trust me son(I have my eye on bigger things -)

Other notable corporals,
Napoleon, Hitler, mmm I must be missing a few.
