My husband is currently a 14E looking to go into THAAD. What are the additional duty stations we could potentially go to?

Well, the obvious is FT Bliss, TX. Just ask your husband to ask his branch manager where y'all could go if he goes THAAD.

As a 14E with the 7A ASI. Hood or Bliss stateside. Guam and Korea are the only OCONUS non dependent restricted. Additionally he may go to a FBM site, which they typically send Soldiers for their first assignments.

Your choices are slim with any ADA MOS. Sill, Bragg, Bliss, Hood, Germany, and Korea and the normal “go-to” duty assignments.

Have your husband log into FMSWeb and he can see all the THAAD locations for his MOS

Guam, Korea, Fort Hood, Fort Bliss, Forward Base Stations-Japan, UAE to name a few.

I can only share so much so keep that in mind. I will share as much as I can.
Things are a little janky right now but basically Japan, the Pacific Rim and Eastern Europe. The Pacific theater is the most likely answer right now, but things are changing from day to day. There is a possibility of Army shipboard deployment on seaborn platforms.
Thank your husband for his service and thanks so much for what you do to support him. It's incredibly important.
