More SS units including “Honour Brigades” would be awesome. To give an example: An SS honour unit on the Russian front had tens of thousands of men. All were wiped out but one man on a 37 or 88mm gun. (They should add those guns to the game) His entire squad was killed including the other 2 men that were helping him fire the cannon. The Russian tanks were shelling and advancing with thousands of men. He stould alone with a pile of bodies and loaded these heavy shells himself and continued to fire the cannon that normally took 3 men to operate.
Long story short, he took out 12 tanks and around 3-500 men as they drew within less than half a mile of him. Reinforcements unexpectedly arrived and helped him push back the Reds. His saviors (An SS bridage) was astonished he had not left his post. He was decorated with the Knights Cross.
Also it would be cool if the German planes had more of an impact on the game and cost more accordingly as the Luftwaffe had the best pilots in the world. (Refference Erich Hartman who holds the world fighter pilot record with 352 confirmed kills. Mind you, that’s just ‘confirmed’. Read a synapsis of his amazing story at:
