U.S. Navy for 28 years (so far) and started as an enlisted, made Chief Petty Officer (E-7) then got commissioned via the Limited Duty Officer (LDO) program in 1999 and am now a Commander. My designator is Submarine Electronics, have served on 3 submarines, 3 surface ships, 2 tours as an Officer in Charge (OIC), and 2 tours as Executive Officer (XO).
Still having fun and love what I do so retirement is hard to consider at this time. Could be within 3 years but am currently chasing the rank of Captain so might stay for a while longer and see if I want to make a career of it. ;-)
Son of a 2 tour Vietnam Vet who was an enlisted door gunner gone ROTC and retired as a Major in the Army and his brother remains MIA (helo pilot went down in Vietnam).
God Bless all those that have served and those that currently serve.
