Okay hear me out:
You call it in as a Cruise Missile truck, leave it circling in your spawn and firing off missile volleys as needed.
Once you've emptied the missiles, you can either recall it for the refund, or leave it loitering a little longer until the other side tries to push, then you send it in as a one-way cluster bomber. With 12 JSOW it will delete all vehicles in a huge line, so it's basically guaranteed to kill multiple targets so long as multiple targets exist to be killed.
>but isn't 600pts expensive for a cluster bomber.
Aha! Less than you think.
The full complement of cruise missiles have a resupply cost of 440pts, which means this plane RTBs for a refund of only 160. After it has used its cruise missiles, you are left with a 160pt cluster bomber, and it's very very easy for 12 jsows to kill more than 160pts worth of targets. With 30 hp it's very likely to survive long enough to drop its payload and because it's a loitering bomber you can save up enough while it's lobbing cruise missiles to call in some SEAD when it's time to make the cluster run, at which point it's likely to actually survive and rtb anyways.
