Taiga Worlds Campaign

The Taiga Worlds Campaigns is an Imperial castigation campaign carried out by the 203rd Combined Siege Regiment against the recalcitrant Taiga Worlds. This campaign is notable for being fought in a 'Zone Mortalis' environment, one of the deadliest environments encountered by Imperial forces, as well as the extensive loss of life and the heavy use of both armoured and siege warfare tactics that comprised much of the campaign's separate battles.

History
The Taiga Worlds Campaign is was characterized both for its environment and the excessive loss of life that accompanied the armored and siege warfare that made up much of the campaign’s battles. All four regiments that would eventually be reformed into the present 203rd Combined were part of the initial spearhead landings into the system and participated in the Siege of Onyxburg. After several months under siege and isolated from Imperial forces, all four regiments suffered severe casualties while on the defense and would later be reformed into the 203rd Combined.
