Once the paratroopers land - they hunker down until there's a group of four on one side to attack your base. Once they're in attack mode the helicopters stop coming but the jets keep bombarding your base. The difficulty of the game is skewed towards missiles - maybe something to tweak.
Hmm, yeah that's a bug. If the game looses focus the wave resets. I'll see about fixing that. If you don't interrupt focus the helicopters and paratroopers should enter the scene. Thanks for the feedback though.
