Backround
The M-78 Kilgore Main Battle Tank is the first domestically designed MBT in Binarian history. Designed to replace the current MBT in service, the LY4 Wolfhound, which is an exellecent tank, it has been decided recently to phase out as many forgien designed equipment as possible with in 10 years.

Engine
The M-78 Kilgore has a powerful 18 cylinder 3000 hp deisel engine in a "V" configuration.

Armament
The M-78 Kilgore's primary weapon is a 130mm/65 cal ETC smootbore cannon. This weapon can place rounds with high accuracy out to ranges of 4200 meters. The long rod penetrator will still be able to destroy or disable medium tanks and heavier IFVs and ACPs at 5000 meters, although, agianst other modern main battle tanks, the chances of killing nuts, are significantly reduced. The High Explosive Anti-Tank rounds use a tandem warhead intented to reduce the effectiveness of Explosive Reactive Armor(ERA). Because HEAT rounds don't need to have as much speed at impact, the killing range against modern MBTs is increased to 5400 meters, although accuracy suffers at this range considerablely, a fair amount of luck is needed to deliver a kill.

-Secondary Weapons
In addition, the M-78 has a considerable secondary armarment with a 14.5x105 mm hatch mounted machinegun manned remotely by the commander, and a 9x76mm coaxial machinegun.



Bismarck Armor Scheme
The Bismarck armor scheme is the result of several decades of research into armor materials and their applications by The Peoples Freedom government and private agencies. The program originally started in 1970 with the introduction of the 'Nova' Main Battle Tank which was the nations' Principe MBT up until the adoption of the Nakil. The result of lessons learned with fifty years of Nova was put into a multi billion dollar program called the Enhanced Protection Scheme or EPS. The primary contractor of this scheme was the Army's Advance Research and Development Lab. Later companies to join was Blitzkrieg Land Systems and Krupp Industries. The Imperial General Staff was the primary funders of the project, with generals reportedly spending personal money and being the primary lobbyists for earmarks.

General Scheme
Bismarck armor scheme in its basic form is designed to reduce the threat of the modern kinetic penetrator to the tank as well as other threats such as mines and shaped charges. The design is also meant to be modular, with easy replacement of perforated plates and high updatability. In fact, while the design was originally introduced in 2022, it would served until 2045 ending with the Mark V scheme. Thus, the armor would continually be updated for two decades.

The first layer of armor is a specially designed Heavy Explosive Reactive Armor set [HERA] which is meant to provide high levels of protection for the tank with little gain in weight. The HERA, named “Rainbow”. “Rainbow” uses a system of operation whereupon the offending projectile in engaged by the “rays” of the HERA and thus deflecting the projectile or in some case managing to actually slice LRP in half thus drastically reducing penetrating ability. The system is composed of “bricks” making each “brick” easily replaceable once used, in addition the “bricks” are lightweight at around 3kg and this allows them to be positioned on all areas on the tank, albeit Bismarck Mark I only uses them on the frontal arc and turret sides and mantlet.

Passive armor consists of a ceramic mix backed up heavily by heavy metals. Bismarck relies on Boron Carbide sandwiched between layers of Improved Rolled Homegoues Armor or IRHA. This system, being physically the thickest on the tank at around 400mm in actual thickness, [At least on the Kilgore] allows for the defeat of shaped charge rounds and long-rod penetrators. This is not one large plate but rather a series [3] large plates interlocked to support each other and provide mutual protection. This also allows for somewhat easy replacement of shattered or cratered plates. This layer is also angled at 45 degrees, this helps to “deflect”long-rod penetrators along another flight path and disrupt shaped charge jets.

A second layer of passive armor is located in the rear of the first armor and consists of a variety of “bricks” which consist of depleted uranium encased by IRHA. This would most likely stop any surving long-rod penetrator or plasma jet due to the decreased speeds from the previous layer and the hitting of hard metals. All of these bricks also interlock and provide mutual support while remains separate blocks.

However, the armor scheme along the frontal arc of the tank and along the turret and glacis is very heavy and cannot be expected to continue along the sides and rear of the tanks. Thus, the side of the tank uses the side variant of the Bismarck scheme. In this variant, the primary protection is provided by IRHA which encases fiberglass or “S-glass” which is a lightweight solution that offers significant protection. Behind this layers is the same depleted uranium bricks as the frontal arc but fewer such bricks. A final layers is Light Explosive Reactive Armor which is also lightweight and used in the same brick format as Rainbow. However these bricks are not as thick or lengthy and thus do not offer the same protection. Despite this, Bismarck retains excellent protection against side threats.

The rear of Bismarck cannot offer very much protection due to the weight constraints,and thus most protection will have to rely on the interior of the tank it is used on, such as whether or not the tank has a engine, fuel tanks, or electronics to block the entry of a round. The basic Bismarck scheme provides protection against small arms fire, but additional protection against 30mm autocannon fire is provided by non explosive reactive armor bricks and a 40mm plate of IRHA. The NxRA bricks also offer multiple hit capacity.

Spalling is a perhaps the most dangerous threat and this is countered to a great extend by a thick [15mm] of Spectra, which provides significant protection against such a threat.

Top-attack rounds and mine threats are always of serious concern to the designers of armor protection. For top-attack rounds, any tank must rely heavily on its APS, but additional armor is provided by the Bismarck with NxRA brick mounted on the turret roof. These thick bricks allow multiple hit capability against threats such as explosively formed penetrators, and thus is the most effective lightweight solution that can be provided. Against mines, Bismarck uses two 15mm of IRHA thick plates on the floor of the tank. These plates are separated by a spaced layer consisting of air, gear storage, or an additional “S” glass layer. The inner plates are also lined with Spectra. Bismarck recommends that tanks users also install shock- seating and a plate on the bottom of the chair to further protect crew against fragments.
