Serving as scouts and messengers, the cohortes speculatorum filled the role of spies within each legion. Normally ten in number per legion, Mark Antony created a special group of cohortes who specifically served around him, carrying out personal instructions and protecting his well-being, essentially acting as an early secret service – a concept which was further developed during the empire under Augustus.
