Mechanicum Battle Group Battleforce Description
The Mechanicum served as the forerunner to the Adeptus Mechanicus faction in the Warhammer 40k universe, operating during both the Great Crusade and the Horus Heresy. Despite having full rules support for the Warhammer: The Horus Heresy, its units were previously exclusively offered as costly resin-cast miniatures.
The Mechanicum Battle Group box includes six agile Thallax Cohorts, twenty Adsecularis Tech-Thralls, two formidable Castellax Battle-automata, and a sturdy Triaros Armored Conveyor.

Thallax
Thallax are cybernetically enhanced warriors used by the Mechanicum. These units are tougher and more resilient than standard human troops due to their extensive augmentations and bionic enhancements.
They can be equipped for both ranged and close combat, typically carrying heavy chainblades and lightning guns. They serve as shock troops capable of rapid deployment and are especially effective in hostile environments that would be lethal to ordinary humans.
Their role is crucial in Mechanicum armies, providing mobile firepower and a durable presence on the battlefield.
Tech-thralls
Adsecularis Tech-thralls are cybernetically enhanced infantry units used by the Mechanicum. They are relatively inexpensive troops, making them ideal for bulk forces. Typically armed with a variety of basic weapons, they are not particularly formidable in small numbers but can be overwhelming in large squads.
Their primary role is to serve as cannon fodder or to secure objectives through the sheer weight of numbers, supporting more powerful Mechanicum units by absorbing enemy fire
Despite their lack of advanced skills and equipment, these unsettling puppet conscripts possess an unwavering determination and often overpower vastly superior forces through their sheer numbers and relentless resolve.
Castellax Battle-automata
The Castellax Battle-automata, are equipped with a range of weaponry suitable for different combat roles, from heavy bolters to siege wrecker arms, making them highly effective against both infantry and fortifications.
Designed for resilience and firepower, Castellax units serve as the backbone of Mechanicum forces, capable of executing complex battlefield commands and adapting to dynamic war environments.
Triaros Armoured Conveyor
The Triaros Armoured Conveyor is a formidable transport vehicle designed to carry up to 22 units of your army, including the bulky Thallax with their special rule.
Designed with heavy armor and a unique conveyor system, the Triaros excels in safely delivering troops and war material through intense battle zones. It features advanced armor plating capable of withstanding severe punishment, and it is equipped with a built-in flare shield to safeguard your precious cargo during transit to the front lines.
Thallax Cohort
The Thallax are cyborg soldiers who have undergone a transformation process that involves housing their major organs, nervous system, and cerebrum within armored bodies called the Lorica Thallax.
Despite having their pain centers and emotions removed, they retain a degree of independent human thought, making them more than mere automatons.
