I want a tank, but its actually a helicopter and and, you can have redneck pawnee on your tank and and miniguns, Oh and add a flare gun minigun.
But in all seriousness something me and a few other cops have really wanted for a long time is more ways to smoke out objectives, If you could rig a drone to shoot white covering smoke grenades that would be awesome. Originally the idea was posted as a mortar for smokes. But you can't really script that I don't think. Police don't need more ways to murderize people and I'm terrified to see cops with 30m Pawnees.
