Help with firing smoke

[Kool Kat]

Hey Shep:

Select the artillery gun... hold down the alt key... move the cursor to where you want to deliver the smoke round... than click the right mouse button to mark a smoke barrage. :)

You can also click the "U" button to see the available number of smoke rounds... and to confirm that you toggled it correctly to fire the smoke round.

User Manual pg 41 "Laying Smoke" also gives instructions on smoke ammunition.
