>The wealth and power of an Oppressor is not necessarily in his skill at arms, but in the amount of wargear, slaves, and territory he owns. This has lead to a complex internal economy within the warband and the emergence of actual trade systems within worlds they conquer.
>Any world they conquer is immediately divided up into fiefdoms, and each Marine above the rank of Line Marine granted at least some domain over which to exploit. The entire economy and infrastructure of the world is then turned to the manufacture of their weapons, armor, and other war materiel, and the population reduced to little more than slaves overseen by Marine taskmasters.
>Tactically, the Oppressors use conventional mortal forces to absorb the brunt of an assault, then use smaller units of Chosen, Havocs, Raptors, and Armored Fists to punch through weak points and butcher the foe. Mortal forces are heavily focused on massed infantry, tanks, and artillery units, with the Oppressors free to specialize as they see fit. Marine "Taskmaster" units will oversee mortal operations in critical junctures and command squads, ensuring their will is enacted without question or hesitation, as well as bolstering their ranks with additional firepower.
>Favored weapons are power mauls, Flamer weapons, bolt weapons, chain axes, and Autocannons. Chain iconography and human bones are extremely common motifs, with the white armor of the Oppressors glazed in a film of ritually-prepared powdered human bone before every battle. It is also common for Marines to wrap their forearms and skulls in razor-wire.
>Preferred enemies are other humans, but they have a special, personal hatred of Arbites and the Inquistion. They have also recently plundered the minor Tau world of Vi'Sun, and have uncharacteristically put its large Gue'Vesa population to the sword while taking minimal slaves.
They are pretty cool. Just got started on them, and I'm currently trying to figure out how t do bone-white.
