How to address an officer that is an Army doctor?
I had a question on how to address a doctor in the army. I am throwing a formal birthday party for myself in the next month and half and I am just starting to put my list together for my invitations. One of my girlfriends is dating a Captain in the army and he is also a doctor, this would be my first time meeting him. I want to invite him but how should I address the invite? Do I address it as Captain Doctor Henry Adams, Captain Henry Adams, or Doctor Henry Adams? Or is there another way the invite should be address? Its a formal black tie occasion so I want to address all my invites the proper way. Also when I address him at the party and introduce him to people should it be by his rank and doctor or just rank?
Thanks for the help.
