Posts from How do you split troops into smaller groups? Auto-translated

I remember that in the third Heroes game, there was an option to split one of your military units into smaller parts (equal or unequal, or into several parts). Here, I can't find it. For example, I want to give 10 out of 15 mages to another (my) hero, and I don't see any icon for that...

Hold down Shift and move.

Yes, it's done with Shift. We've told you so many times.

You could just search for it.

Thanks.

Don't be too hard on me, guys, you can see I'm a newbie.
P.S. I'll do it this way from now on.
