It would be cool if we could send units out on patrol?
Option 1: Free-roam - Units can go anywhere.
Option 2: Free-roam - Kilometer Radius - Units can patrol anywhere within the defined radius.
Option 3: Way Points - Looped Waypoint - User defines a path for each vehicle and the vehicle goes on patrol on this way points and keeps doing it until called into action
Option 4: Way Points - Single Waypoint - User sets a path that isnt looped, once unit reaches the end, it goes back to station.
