Just Some Imperial Guardsman
The Astra Militarum, the human footsoldiers of the Imperium’s armed forces, are Just People. They’re not supersoldiers like the Space Marines, they’re meant to be a shield of meat butchered by the platoonful defending the Imperium’s worlds from nightmarish threats, firing their piddly lasguns and hoping for the best. They’re dwarfed by their enhanced allies and foes alike, and it’s rare that a Guardsman has a long career, or retirement. So putting Henry Cavill in a set of their standard issue boots having him be a tiny regular dude would be very fun.
