Sorry if this is the wrong place for this question, but it did not seem to fit anywhere else.

With the army Builder I sometimes get a S in the troop name column. Hovering over this changes the troop type, but I cannot see how to make this permenant. As soon as I move the mouse, the troop type reverts back.

Can anyone help please?

Thanks
Philip

The change is made in deployment i.e. after you have started the game.
By right clicking on a BG you can change it (and back if you change your mind).
After deployment you're stuck with your choice.
