Officio Logisticarum

The Officio Logisticarum, also known as "Guilliman's Hand," was an agency of the Imperium of Mankind created on the order of the Lord Commander of the Imperium Roboute Guilliman during the Indomitus Crusade.

The Officio Logisticarum was an attempt by Guilliman to go around the massive and ponderous Imperial bureaucracy of the Adeptus Administratum in the late 41st Millennium so as to rapidly build up the materiel needed to launch and resupply the galaxy-wide Indomitus Crusade.

History
To bring the Indomitus Crusade to fruition, the Primarch chose to bypass the established Imperial bureaucracy entirely. Guilliman created his own elite cadre of facilitators whose role was to ensure proper supply and marshalling of every single starship and soldier for the crusade.

Named as the Officio Logisticarum, but known throughout the crusade fleets as "Guilliman's Hand," this body was millions of souls strong, its members drawn from the best that Terra's Administratum and Departmento Munitorum bureaucracies had to offer, and still it was barely equal to the task.
