Groundcars are civilian ground vehicles.
The Terra Cougar is a heavily armored ground car. It was developed by 2458 and in use for at least twenty years after that, though was considered an older model. It was frequently used to protect politicians from assassination, courtesy of a heavy steel undercarriage, polarized armored glass and thick side panels. Turret-mounted Impalers can be attached to them and a comm. unit features for passenger use.
