My son's next step in the AROTC app process is to schedule an interview with the PMS at a school of his choice. The PMS is a LTC. So, what does Son use in the greeting of his email request? "Dear LTC Smith?" "Dear Lt. Col. Smith?" "Dear Lieutenant Colonel Smith?" "Dear Col. Smith?" Then, once they meet in person, how should he address the PMS? Lieutenant Colonel or Colonel? I'm sorry if these are stupid questions. But, we have NO military personnel in the family. Really, none. (My GF served in WWII, but he died in '88.) All I know about addressing LTC's comes from M*A*S*H* and, IIRC, Radar didn't use "Lt" with Henry Blake even tho that was his real rank.
