It seems likely that the original list was padded out with allied choices from the chaos space marine codex in order to enable players to collect a playable army in time for the Eye of Terror campaign, so now that latd players have had enough time to collect a full army, various marine units have been removed and replaced by many more non-marine units. This codex is based off the original Lost and the Damned codex, with updates to take into account the changes to the imperial guard’s layout and the new units, as well as to take the focus away from the marines side of chaos.
