What will likely happen to the 173rd unit in Germany?

If it is being deactivated, those in it could always cross train for a different MOS,or be absorbed by other units with the same specialties.

I read that it is going back to Italy.

Isn’t the 173rd primarily at Vicenza?

They’ll eventually move them to Italy. The current plan is to withdraw 12,000 of the 36,000 Germany troops and move 5,600 of them to Italy and Belgium. Two thirds will still remain in Germany

Wouldn't be the 1st time they were either deactivated or posted to Italy

A lot of questions are still out regarding this issue. I am eager to see how it all turns out over the next few years.

Specifically the airborne part.
