The 8th company is one which is most rapidly deployable as a whole company within the structure of the Adeptus Astartes Chapter organisation. It consists entirely of assault squads and some specialised units associated with command, control, logistics and specific assault roles. Detachments are usually deployed to augment other battle companies at crucial points in the attack or counter-attack.
This list assumes the occasional situation where a large detachment containing it's own generic command structure or even the whole company might be deployed during large campaigns. It is based on the Dark Angels Codex, but can be adapted towards C:SM by simply altering the point values of characters. In game terms this list is aimed at those playing "Big Fun Games" of 5,000 points or more, where a detachment from the 8th Company may join other standard forces.
