Formed in the 27th century, the Dinochrome Brigade was the Concordiat 's overarching unit for Bolo forces during the latter half of its existence. It was originally made up a number of independently operating regiments that served alongside Concordiat Marines and planetary militia forces. Around the 32nd century, the force was re-organised into a number of independent Brigades although lone battalions of older Bolo models were often employed in secondline roles and regiments remained an important sub-unit.
