make one set of waypoints for your truck and another for your troops. where your troops get in the truck have a truck waypoint of type "Load" and a troops waypoint of type "GetIn". Synch these two waypoints. Where you want your troops to get out have a truck waypoint of type "Transport Unload" and a troops waypoint of type "GetOut". Synch these two waypoints. Once your troops get out they'll follow the rest of their waypoint path. Incidentally, no other waypoints in the troop path between the getin and the getout.
