Oooh a dog handler would be fun! I am in the army here part time as a combat medical technician lol, lots of fun to be had! Follow your dream if that's what it is, half of it is plucking up the courage to take the first step. My husband has been in the army since we left school, so 6 - 7 years now, and he still enjoys it, so it's not all getting screamed at etc lol!
