I had a look, using the battle setting, and I found that sometimes Syria would have air strikes, and sometimes not. I tried at 1967 and also 2000. I also tried for the US, USMC and UK in 1967, and they did not always get air strikes.

They exist in the OOB, per mobhack.

The manual seems to imply that air strikes are not always available - in places it says "if" you are allocated air points.

I also read that if visibility is low, you may not get air strikes, especially in earlier years. And the visibility setting was low when I was trying this out.
