How do you rally units?

[Lord of the Isles]

Ahhhh....where's the "rally" button?

I thought it had been eliminated. Units seem to rally on their own.
In the Demo I recall clicking away, but it never seemed to work.

It's the special abilty of General units, so when you want to try it click in the "special ability" button in the bottom right box (it's a brown horn icon if memory serves).

Like others, I've had limited success using it.
