H.A.I.S.V. (Heavy Assault Infantry Support Vehicle) aka The Apocalypse

The HAISV is a multi-role vehicle based on the original Snow Cat chassis. It has been modified from its original arctic domination role to that of a vehicle usable in more than one environment. For use in non-arctic environments, the rear track and drive system has been replaced by a set of heavy duty, reinforced suspensions systems and weight distributing wheels.

The rear suspension has been upgraded from the original Snow Cat design to accommodate the added weight of the turret and weapons systems. In addition to the upgraded suspension, the rear tracks have been replaced by four large wheels. In lieu of traditional tires and rims, the wheels are made up of large steel rims with solid rubber segments that can be removed and replaced as need be instead of having to change out an entire tire. The front tires are thicker, more bullet resistant rubber and have a run-flat system installed within.

All other systems and function of the original Snow Cat chassis remain the same or have been upgraded as needed.

The vehicle can work in all weather and environments including working in areas contaminated with NBC (Nuclear, Biological and Chemical) weapons. The cab is completely sealed and climate controlled and a soft canopy can be pulled over the commander's station for chemical weapon protection. The Assistant Gunner would need to resort to having to rely on his field protective mask and MOPP (Mission Oriented Protective Posture) gear.

The weapons systems consist of two Browning M-2 50 caliber machine guns, two TOW missile launchers, four turret mounted 25mm Bushmaster chain guns and various man portable weapons systems. The weapons systems of the vehicle runs through redundant systems and can be operated by the gunner in the turret, the missile technician in the right seat of the cab, and in limited capabilities, the driver.

The four shot missile rack mounted on the rear of the Snow Cat has been replaced by an armored body with a turret. The turret houses four 25mm Bushmaster Chain guns. The vehicle's commander sits within the turret and has full access to all weapons systems from there.

Two LOSAT (line of site, anti-tank) TOW (Tube Launched, Optically tracked, Wire Guided) missile launchers have been added to the outside of the main body and replace the ski-pedo mounts of the Snow Cat design. The optics for the TOW missile system has been mounted on the left side, above and behind the cab and can be targeted via a HUD (Heads Up Display) located in front of the Missile Technician's seat. Loading and reloading of this system is handled by the Assistant Gunner. Extra missiles are stored in the rear of the vehicle.

A pair of Browning M-2 50 caliber machine guns have been mounted on either side of the cab on the fenders. Their ammunition supply comes from and ammo drum located underneath and behind the driver and passenger seat. Feed trays guide the ammo from the drum, up the inside of the cab, through the wall of the cab and into the gun's receiver. The M-2 was chosen for this application because it has the capability of being converted for both left and right side ammunition feed. The M-2s are used for firing straight ahead and can be operated by any member of the crew from any position. Their convergence point is between 500 and 520 yards in front of the vehicle.
While mounted on the vehicle, the weapons are fired by use of an electric solenoid, similar to the triggering system of aircraft mounted applications. They are designed to be removed from the fenders and used by the crew for non-mounted applications and tactics and can be removed from the vehicle in less that a minute. The weapon's tripod is located in a storage area to the rear of the vehicle.

The crew of the vehicle is ideally four, but it can be effectively be operated by a crew of two. The crew consists of the Driver, the Missile Technician, the Gunner/Commander and the Assistant Gunner. Depending on the mission, a communications specialist/radio operator will augment the vehicle's crew.

The Driver is responsible for operating and performing first echelon maintenance on the vehicle. During combat operations, he follows the orders given to him by the vehicle's commander. Should the other members of the crew be indisposed, the Driver can fire the two M-2 50 cal machine guns by use of paddle style triggers located on the steering column. Because of the configuration of these weapons, he must point the vehicle at his target.

The Missile Technician is in control of the TOW missile system. Sitting in the right seat of the vehicle's cab, he sites the weapons system through use of a HUD (Heads Up Display) projected in front of him. He has control over the fender mounted 50 cal machine guns and limited control of the turret mounted guns should the Commander become indisposed.

The Commander/Gunner is in command of the vehicle and is the ranking crew member. As the gunner, he uses the turret to engage targets on the ground as well as slower moving airborne targets such as helicopters or fixed wing aircraft on landing approach or take off vectors. The Commander can control the TOW missiles using a targeting system located within the turret. The commander can also fire the M-2 50 cal Machine Guns. Should the crew of the vehicle be reduced to two members, the Driver and the Commander/Gunner are the two positions that need to be filled for combat operations.

The Assistant Gunner (A-Gunner) performs all secondary actions for the vehicle, consisting of assisting the Driver during maintenance and cleaning the weapons systems as well as reloading the weapons during combat operations. The A-Gunner rides on the back using hand and foot holds. For longer trips, the A-Gunner can strap themself to the vehicle to reduce fatigue on their hands and feet or, depending on the mission parameters, they can ride within the weapons storage area in the rear, although the area is rather cramped.

The HAISV is used in multiple roles which include Convoy Escort, Base Security, Infantry Support Vehicle, Tank Hunter, Ambush and Recon.

During Convoy Escort operations, the vehicle takes the lead or the second vehicle behind the point vehicle and provides frontal security.

For Base Security, the vehicle patrols the area and can fire upon incoming attacking aircraft or ground vehicles.

As an ISV (Infantry Support Vehicle), the vehicle supports the infantry with suppressing firepower, allowing the infantry to advance on the target and can be used, in limited capacity, to remove wounded infantrymen from the battlefield.

In the Tank Hunting (Hunter/Killer) role, the vehicle, working alone, or in a pairs hunts down and destroys enemy tanks and armored vehicles. The rear storage area contains an assortment of man-carried anti-armor weapons including SMAWs (Shoulder Launched, Multipurpose Assault Weapon), Dragons, and Stinger missiles.

Ambush missions require the vehicle to work alone and undetected. The vehicle can be set up in an ambush point with the weapons pointed in the direction of the enemy approach. The M-2 50 cal Machine Guns can be removed and set into position and can be augmented by a MK-19 40mm grenade launcher and other weapons stored in the rear area.

In Reconnaissance operations, the vehicle moves within a designated area and uses the video/photography capabilities of the optics systems.

The vehicle has been nick named "The Apocalypse" by the troops as it is known to be the end of the world for the enemy and the four crew members are referred to as "The Four Horsemen."
