This is a minor, but rather important quibble I have right now. Unlike the Skyranger, the Chinook doesn't have global range, which means in the first couple of months, there is a very high likelyhood that a Terror Site will pop-up in a place you can't respond to at all and it costs you a ton of goodwill from the funding countries. This can happen sometimes 4 times in a row.
With the chance for air interception now by hostile alien fighters, Chinooks should be given global range and use the reason of in-flight refueling or stopping in airports or FOBs to refuel. If a player is willing to risk their team in a slow helo with no escort, that should be the chance they take.
