Active duty officers: Where did you get your Masters Degree?

This is a survey based on another question asked by an NCO about why NCOs aren't afforded time in their career path to get a masters degree. I think that most officers do it on their own time and not on the Army's, but I could be way off. When and where did you get your masters degree if you have one. Just the active duty officers (counts if you were active and got one but are now retired). Certainly not scientific, but I'm curious now. I'll add another one to balance for the NCOs. I forgot to add an option to the survey if you don't have one. If you never got a masters while on active duty, just add it in the comments without taking the survey.
