Changes

The unification of human worlds did not always proceed without incident, as not all lost worlds showed immediate interest in making themselves subservient to the Imperium. In these cases, compliance with Imperial directives was enacted with the use of military force. These situations, as well as the ever-present alien threat, resulted in Expedition Fleets having a strong armed contingent, and were usually being under the command of a military officerof the [[Imperial Army]], a [[Lord Commander]]. In addition to a Lord Commander, each Expedition had a [[Master of the Fleet]] who was in charge of the Imperial Navy ships in the Expedition. Each of the [[Primarchs]] was able to, and often did, command an Expeditionary Fleet, attaching to it the majority of their [[Legion]]. Most Fleets had no [[Astartes]] presence at all, although some Primarchs split their Legions into small detachments that they parceled parcelled out to various expeditionary forces.
