Are they not released directly over town 800' ft and above, then drop down onto ground. Or are they instantly counted as they hit 800ft' height? They can be shot and air cargo is considerably more visible to target.
Trying to take a base, flying around town taking it down only to have it pop up by invisible feeding vehicles. No combatant's other then door dash deliveries. I would of let attackers take base rather than offer such lameness, but then I have bad habits.
