I also posted under military section, but I thought some etiquette experts might know too. Outside references welcome!
We've got a few couples who are both active duty military, and some that are split. How would you suggest addressing:
Married couple, both Captains (or any other rank)? My thought: Captains John & Jane Smith
Married couple, they both carried the rank of captain, but he recently split from service? (Is it the same as above? I'm not sure how to handle rank for military who are out of service. This husband got out (didn't retire), I'm assuming at least retired military continue to carry rank).
Unmarried couple, both LTs - MT: Lieutenant John Smith & Lieutenant Jane Jones
Also, I believe all rank should be spelled out fully, correct? As in not M SGT John Smith, but Master Sargeant John Smith?
Thanks for any input!
