Basics
The viper is essentially an extremely scaled down tank. The Viper incorporates a design plan based upon the T-72, except it uses mostly the materials that M1A2 Abrams. The armor is the same composite armor used within the M1 Abrams, and the Primary Cannon still uses the round used in the M1A2 Abrams. The Tank is scaled down, but still possess a massive amount of armor. Because of this, it cannot move at very rapid speeds, and can only travel a max of 24 mph, with it's cruise speed being roughly 18mph. It also has a limited range, although a large amount in concurrent with it's speed.
The tank is a single crewed manually operated device. The Tank is steered and controlled to move forward with the feet, this directing direction and speed. This is controlled by a series of small pedals, which include the accelerator and a brake. Although the speed can be set into cruise mode through an electronic pad that designates the speed, resembling that of a PDA to the side of the user in a small chair. The brake automatically turns off the cruise control. The user sits in a chair, and views the outside world through a screen which has several cameras on the outside presenting the external views. Despite the oddity and loss of ergonomics by it, the user sits roughly in the middle of the tank, which is lead into by a hatch through the center of the tank. This of course leads to the seats and the screens.
Alternatively, a helmet, like one used in the Apache Helicopter can be used to view the outside world through the series of cameras on the outside of the tank.
