Air units?
 

OK, during my campaign setup, I toggled on three air sorties.

Is there another thing that I must do to make these available?

For the US, 2008 campaign vs. Iran, I had access to helo's, but not to A-10's, and other CAS aircraft. Are they even purchaseable?

Thanks. I know the answer must be in 100 different spots...darned if I can find it.

Check the Weather for that battle. Sometimes Weather will effect if a plane is available.

The key word here is "campaign". Player points (apart from P1's setting at the initial core purchase screen point) and air strikes settings have nil effect in campaigns. The campaign code assigns the air as it sees fit, battle by battle or if a user-designed campaign or a scenario then as the designer saw fit.

The air strike settings are for random battles in the battle generator only.

Did you look in the misc screen for the air strike elements?.
