Check out the incredibly badass Dillon Tactical Vehicle.
What looks like a standard black SUV is actually the deadliest vehicle on the road.
Used to provide protection for VIPs and convoys alike, the DTV features a mounted Dillon M134D hidden inside.
When a show of force is required the mounted gun pops out of a hole in the roof. The weapon can be fully depoloyed and operational in under 5 seconds.
The swivel carriage allows the shooter a full 360° of movement.
