No. They aren't. They are two vastly different regiments, just because they have gasmasks doesn't make them anywhere near the same. It's like saying The Kanak Skull Takers are the same as the Catachans, that the Elysians are the same as the Fellesian Airborne because they both have Grav Chutes. The battle doctrine between the Legion and the Death Korps are so vastly different it's not comparable - Siege Warfare/Attrition opposed to Mechanized Assault.

Quartermaster Colonel May, Commanding officer of the Krieg 22nd Siege Regiment, 12th Line Korps, 88th Siege Army. I serve the Emperor with every fibre of my being, I exist only because He allows it, I fight for Him for the continued existance of the Imperium of Mankind and to repay the debt that Krieg owes Him. Evidently, I like the Death Korps of Krieg, I serve in the Krieg 22nd Siege Regiment and also in the Death Korps Quartermaster Stores. I like 40k alot, espiecially Imperial Guard, I have 21,000 points in my Death Korps of Krieg Regiment. I also have Armaggeddon Steel Legion, Cadian Shock Troops and Moridan Iron Guard. I play a multitude of games, ranging from every Dawn of War game to Garrysmod.
