Husband in iraq and i got a weird phone call?

I checked my husband's cell phone for any missed calls this morning and it had one. The number was from Ft. Myer, VA. I spoke to the man on the other line and he said that he was just calling my husband to advise him that Ft. Myer, VA was gonna be his next duty station. Which makes no sense to me cause my husband is deployed and has a while left before he returns stateside. This phone call just really confused me. The man on the line also told me that he got spoke to my husband. Could this be some type of mistake? But if it is how did they get his name and phone number correct. Should I do anything? I mean there's nothing I can do but I guess I'll just wait until my hubby calls so he can make sure that it's a mistake.
