The FAV-22 represents the king of all Federation armour, and has been so since 4 years before the Sol War. An improvement over the older FAV-18, itself an outstanding armoured vehicle, the FAV-22 represents a new step in Federation armour technology.
A modular design, the FAV-22 comes in five primary and numerous secondary variants, all sharing mostly the same chassis and track design. The FAV-22 chassis was build using molecular "honeycomb" heavy armour, which is sandwiched between layers of BSA gel and superfibre. This allows the body to withstand even direct hits from air-launched weapons as well as ground based and man-portable anti-tank weapons. This near-invincible layer of protection is further bolstered by the addition of reactive armour panels across weaker spots on the tank armour. An anti-ordanance, automatic defense system is mounted on the forward hull and aft compartment of the tank, and fires little pellets at inbound ordnance, destroying them before they can do damage to the tank. This defense system has made the vehicle hard to kill by the Allied forces, and a single FAV-22 is always a priority threat.Variants.
The FAV-22 comes in many variants. This guide will include descriptions to the four most common variants.
The Main Battle Tank variants of the FAV-22. It carries a 115mm -calibre railgun as it's primary weapon. An anti-missile point laser defense system is mounted on the top turret, and can target and destroy incoming enemy missiles with an invisible beam of light. Secondary armament is user-configurable, able to mount coaxial as well as turreted machineguns or grenade launchers. Three mounting ports on each side of the turret enables the mounting of grenade or gas/smoke dispensers as well as an added armament of anti-tank missile tubes, making the Sword a worthy foe against Allied "Lightning" tanks. The Sword is equipped with a high-performance electric drive, which can propel it for more than 48 hours non-stop on a single charge.
The 115mm railgun can fire a variety of mission-specific loads, including (but not limited to)
LVHE rounds (Low Velocity, High Explosive)
APDS rounds (Armour piercing, Discarding Sabot)
EHVP rounds (Extra high velocity penetrator)
EHVRA rounds (Extra high velocity, rocket-assisted)
APF rounds (Anti-personnel, fragmentation)
LRAPF rounds (Long-range anti-personnel, flechette)
Rounds of smaller calibre can be used by adding a sabot before firing. This makes the tank incredibly adaptable in most conditions.
The charge-power of the gun can be determined by the tank's gunner to enable him to target enemy targets at various distances and or conditions.
"Whirlwind" Mobile Anti-aircraft.
A variant of the FAV-22-MBT, replacing the turret mount with a modified LT turret. On board the turret are optional quad 40mm, high-altitude anti-aircraft railguns or two CIWS-15-type gattling guns. While the quad-40 mm (often referred to the four-fourties) is able to down enemy craft as high as 2km up (standard atmosphere and pressure, maximum gun-charge), the gattlings are a shorter range defense system, and both can be used in an anti-infantry role as well. In front of the turret is a FRS-114 RADAR system, part of the tanks's MMADAR suite, which also includes thermal and laser targeting systems. The turret also features advanced autotracking systems which can down enemy craft accurately. A point-laser defense emitter is mounted high above the turret, which can protect an entire ground force from enemy attack. In addition, two 6-pack SAM tube mountings (with various mission-specific missiles and warheads) can be mounted on the side of the turret.
The FAV-22-AAA shares the same general chassis as the MBT variant.
"Scorpion" Light Battle Tank
Built for speed and mobility, the Scorpion variant features a smaller, but taller turret that can engage different kinds of land foes (taller turret allows lower-angle shots), quickly and effectively. Built with lighter (but weaker, to a certain extent), combat armor, the scorpion was designed with speed in mind. Capable of being air-dropped from smaller dropships, the Scorpion's main role is to back up infantry battalions as well as hit-and-run operations. Instead of an electric drive, the Scorpion runs on the more powerful (but with higher fuel consumption) gas-turbine engines, that can propel it to an astounding 75 kilometers and hour on flat terrain. The Scorpions carry the smaller, but faster-firing 75mm railgun, and can mount anti-tank missile launchers for an increased anti-armour role, or various other accessories shared with it's larger MBT cousin. The Scorpion lacks the turreted Point-Laser defense systems of it's other cousins, but makes it up with pure speed and manouverbility.
King Scorpion subvariant.
A sub-variant of the Scorpion, the King Scorpion shares all the features with the regular Scorpions, with the addition of additional communications and battle-planning equipment for field commanders using the vehicle, allowing the commanders to keep in touch and control of the tanks he is leading into battle. A more powerful and longer range ORBIS system as well as a superluminal communications array is available on request. A commander verision of the MBT variant is still being designed and has not come into service.
With such a modular and adaptable (if not, expensive) vehicle, many other variants of the FAV-22 is being developed. These include
-CEV (Combat Engineering Vehicle)
-MLRS (Mobile Multiple Launch Rocket System)
-LRA (Long Range Artillery)
-MBT Mk.II (Main Battle Tank, Mark II)
Many believed armor had little utility in Vietnam, but Marine and Army combat experience proved that there was no substitute for the shock and firepower tanks brought to the battlefield. Used primarily in the infantry support role, the M48A3 tank was America’s main battle tank in Vietnam from the earliest combat action, and in South Vietnamese service almost to its last.
The M48 was the final version of the Patton series, named after General George S. Patton. The first M48s were produced from 1952 to 1959, but the Vietnam-era A3 was a modernized and refurbished variant that first rolled out in February 1963. It had a supercharged diesel instead of a gasoline engine and an enhanced fire control system. The turret and hull were made from cast homogenous steel and enjoyed a 60-degree frontal slope. The turret had 4.5 inches of frontal armor, 3 inches of side armor and 2 inches in the rear. The hull’s front armor was 4.3 inches, and side armor was 3 inches forward and 2 inches at the rear. Inch-thick floor plating gave good protection against enemy mines.
The M48’s 90mm M41 cannon fired a 24.16-pound shell with a muzzle velocity of 2,800 feet per second out to a maximum range of 4,500 meters, but the fire control system had a 2,500-meter limit. The gunner used an M17A1 coincidence rangefinder, and the fire control system included a repeater that displayed the gunner’s sight picture to the commander. A coaxial .30-caliber machine gun and a .50-caliber gun in, or mounted on, the commander’s cupola rounded out the tank’s armament.
The M48A3’s wide tracks gave it good off-road mobility, but Vietnam’s exceptionally soft, deep mud frequently bogged it down. Its shallow fording depth (4 feet) and weight could limit its employment. A kit was available that enabled the tank to ford rivers up to 14 feet deep, but it was rarely used.
Patton tanks were in most of the war’s major actions, serving with the Marines and three U.S. Army tank battalions and with Army armored cavalry squadrons until replaced by M551 Sheridan light tanks. As U.S. forces began to depart in 1970, they turned their M48s over to the South Vietnamese.
Although designed to combat massed Soviet armored formations, the Patton was an invaluable weapon for infantry support and defending firebases. It is generally considered superior to the T-54/55 and T-59 tanks the NVA deployed south in 1972 and later. The newer M60 replaced the Patton in regular U.S. Army and Marine units after the war, but the M48 remained in service with most American allies and its reserve units well into the 1990s.
