The 203rd Combined Siege Regiment, nicknamed Skarborovicha's Knights after their current commander, is an elite regiment of siege troops made up of the remnants of the 203rd Valhallan Mechanized Infantry, 47th Death Korp Grenadiers, 63rd Steel Legion Mechanized, and the 454th Cadian Shock Troops following their horrific losses during the battle of Hive Onyxburg. While serving in the final half of the Taiga Campaign, the Combined Regiment -- which was later designated as the 203rd Combined due to its large Valhallan-based officer corps -- served a crucial role during the siege of the fortress Hive of Darwinall.
