Can Employees of NSA shop at Fort Meade Commissary?

No. You need a military ID (active duty, retiree, dependent, etc)

I work at the Commissary, and no you don't need a military ID, what you do need is a valid ID with shopping privileges and post access, so employees of the PX and Commissary who do not have military IDs can indeed shop there as well as ANY NSA employee. So, in short answer, yes.

No, need military id

You need a valid military I.D.

i believe you need the correct credentials...govt ID...or an approved escort
