Ok so here goes. I was reading a white dwarf from well a while back now and i noticed the abhuman doctrines. I read about the lostok 23rd. Basically their're guardsmen on steroids. However the doctrine system was (annoyingly) purged from the latest codex, so the lostok 23rd became just another cool set of rules that were out of date, but no more. Here i will try and detail the troop types of the 23rd as an addition to the Imperial guard army list. Their fluff is that they were sent to fight on a polluted forge world against the nids and had special organs put in place to counter the poison.
