So I want a CAS run to make a clean slate once I have taken out the AA guys and the HMG's in the area.
I tried a trigger with "!alive (unit) &&..." and so on synced with the support provider (CAS Bomber) which the syncs with a A10. Did not work though. Any help would be appreciated.

Use this code in the on activation box of a trigger (condition set to what you want)

support_requester synchronizeObjectsAdd [player];

Synchronize the trigger with the support requester module and as in the example above name the module support_requester. Then Synchronize the support requester module with the support provider module and in turn synchronize that with your A10.

The code basically adds sync to the player when the trigger is activated.

The "support_requester" in the top code is just a name, and can be anything you want, so long as the support requester module is named the same.
