At the outbreak of the Horus Heresy, the Taghmata Omnissiah was the principal type of operational force of the trans-Martian Mechanicum. Incorporating many distinct divisions and sub-cults, a Taghmata on the battlefield could include endless varieties of automata, Adescularis tech-thralls, Thallax cohorts and constructs and war machines of unfettered devastation.
The Mechanicum Taghmata Support Cadre is an excellent way to expand your Mechanicum Army. It includes a Thallax Cohort of three Thallax, a 10 man Tech-thrall Covenant armed with Las-lock rifles, and a hulking Thanatar-Calix class Battle-automata.
