I was a bit disapointed to see that the Kreig and Tallarn regiments just got M36 lasguns. They get specifically different patterns in the fluff. I'm all for treating weapons as the generic version in most cases but when you've got a whole a RPG based on Imperial Guard it seems to take a bit out of it when you assume all those specified lasgun patterns, Lucius pattern, Mars pattern, Voss pattern and Ryza pattern are all treated as M36.
So does anyone have any home rules? Or are they going to go into it more detail in Hammer of Emperor?
