Editing Cadia (section)

===Colonizers===
Cadia's, as you noticed, only real export was soldiers. The thing is, Cadia pumps out so many that they usually form the core cadre of amalgamated units that get clumped into entirely new Imperial Guard armies, and sent to wage campaigns against taken or occupied planets. These armies are never getting sent back home, and are intended, when they win, to form a new government and society, and settle down (as seen in Dawn of War WA and Dark Crusade). As the core is usually Cadian, a lot of the army doctrines and style end up being Cadian, at least for a millennia or so. Hell, they colonize empty planets this way even, especially if it's a dangerous sector of space. Even now, who knows how many planets that are distinct and vital started this way? [[neckbeard|Your DNA could be spread far and wide across the galaxy and you wouldn't even know]].

This is of course to justify why everyone looks like Cadians, aka GW doesn't want to make a dozen different types of guards.
