Cult Mechanicus Battle Congregation
Battle Congregations are the military force of the Tech-Priest hierarchies. The armed force typical of a Battle Congregation consists of a variety of forces from the myriad militant Mechanicum factions under the general command of a Tech-Priest Dominus. The makeup of the Congregation is heavily dependent on the strength of the Forge World and the Dominus' status in the labyrinthine hierarchy of the Mechanicum Priesthood. There are thousands of iterations.
