E-75 Mech Twin 50mm Guns Assault Tank

The E-75 Mech Twin 50mm Guns Assault Tank is a specialized anti-infantry and light-armor combat variant of the E-75 Heavy Mech series. Retaining the Type G's turret design, this version replaces the 128mm high-velocity cannon with dual 50mm autocannons, significantly improving its ability to engage infantry, light vehicles, and lightly armored targets.

With a total production of approximately 400 units, this variant was designed to operate in supporting roles, providing rapid sustained fire against enemy forces while retaining the ability to penetrate light and medium armor. It proved to be effective in urban combat and combined arms operations, where its high rate of fire and maneuverability allowed it to outmatch conventional armored vehicles.

Development and Design

Following the deployment of the E-75 Type G, commanders identified a growing need for a mech variant that could effectively counter infantry formations while maintaining some level of anti-armor capability. The twin 50mm autocannon system was selected due to its high rate of fire, moderate armor penetration, and versatility against both infantry and light tanks.

This design allowed the E-75 Twin 50mm Assault Tank to serve as a mobile fire-support unit, rapidly suppressing enemy positions and engaging light armored vehicles and fortifications. While its 50mm cannons lacked the armor-piercing power of the 128mm main gun, they were capable of flanking heavy tanks and destroying them from the side, making this mech a valuable asset in tactical battlefield maneuvers.

Operational Role

The E-75 Twin 50mm Assault Tank was primarily deployed in infantry support roles, tasked with:

• Suppressing enemy infantry formations using its high rate of fire
• Engaging lightly armored vehicles such as armored cars and reconnaissance tanks
• Flanking enemy heavy tanks to exploit weak side and rear armor
• Providing close-range fire support in urban combat

Its high mobility and firepower allowed it to perform hit-and-run tactics, weakening enemy forces before heavier units moved in for the decisive blow.

Combat Performance

This variant demonstrated remarkable effectiveness in urban warfare, where its fast-firing 50mm cannons could sweep enemy positions, clearing buildings, defensive structures, and infantry squads in seconds. Despite lacking heavy anti-tank capability, it compensated with tactical agility and high-volume fire, making it a crucial support unit in mechanized assaults.

Power and Mobility

The Twin 50mm Assault Tank retained the Type G’s 1,200-horsepower engine, allowing a top speed of 45 km/h, maintaining its mobility despite the weapon modifications. The bipedal walking system remained unchanged, ensuring good terrain adaptability in urban, mountainous, and uneven environments.

Crew and Protection

The E-75 Twin 50mm Assault Tank operated with a five-person crew, including:

• Commander – Battlefield coordination
• Primary Gunner – Controls the twin 50mm autocannons
• Driver – Manages movement and positioning
• Secondary Gunner – Operates defensive systems
• Engineer/Operator – Monitors mechanical systems and assists with field repairs

Armor protection remained identical to the Type G, with 180mm frontal armor, offering strong resistance against medium-caliber weapons while prioritizing mobility and rapid engagement.
