I wish I could call airstrikes down. While it wouldn't be possible in the final mission or base defense/attack missions, it would be nice to know if I encountered sectopods and didn't have the means to harm them, I could paint it with a cruise missile, get the lock, and fire away. Even better, I wish interceptors could be paired with skyrangers, giving players the ability to call in an immediate airstrike. Vehicle weapons are far more powerful than handheld weapons. The alien fusion ball is the only hand weapon that can blow a whole through alien ship hull. The ship version can blow up small and medium ufos in 1 shot. Clearly blowing up is more powerful than blowing a small hole. A simple stingray missile would likely translate 280-490 explosive attack.
Also, I think many players would get a good laugh calling on airstrikes during a terror mission.
