The Guard forms the very backbone of the Imperium for without them, Mankind would surely perish. Yet the actions of these anonymous soldiers daily decide the fate of worlds. Attacking in seemingly endless influxes across battle zones, charging forth under the cover of massive barrages and delivering massed lasgun volleys, in the Guard the individual Human soldier may appear a lost thing, almost forgotten. This absolute numeracy provides the Guard with its main power their ability to deploy in numbers that, eventually, results in victory. It would be unfeasible trying to put any exact number on the strength of the Guard however, it is believed that there must be many billions of Imperial Guardsmen, divided into millions of regiments. The Imperial Guard, also known as the Astra Militarum, is the primary fighting force of the Imperium, so numerous in size that even the Departmento Munitorum cannot place a figure on the number of Guardsmen under arms at any one time the lists of new recruits and toll of casualties can run into the millions in a single day.
