Army Acronyms 2024

Imagine you just married someone in the military, and they tell you their marriage plan. 

Hey sweetheart, I know we just finished our honeymoon, but Monday after PT and breakfast at the DEFAC, we will go to Deers so I can update my CAC and then enroll you in TRICARE. Then we have a three-day weekend after the DONSA. So you can use my POV while I’m going on a ten-day FTX where I will wear my BCGs and eat MREs, and then we will PCs OCONUS with a three-year ADS before we ETS back bonus to use my GI bill to go to ROTC so I can transition from E five pay to one pay.” Did that make sense to you?
