Redeploy anti-air guns?

[VonWulfen]

Hello all.
Commander units have x2 ani-air.
In the unit tab, there is a "Redeploy anti-air guns" button.
How is this used? I tried clicking it thinking it would deploy anti-air but nothing happens?

It is to remove the yellow anti-air guns that are on the map. The guns then show up in the deployment screen the following turn and can be re-deployed to a new map location.

Many thanks sir.

Oh, thank you. I have wondered about the AA-guns.
