"The Imperium of Man cannot have emotion. The Imperium of Man must be as merciless and uncaring as those it fights. The Imperium of Man is not about the people that make it up, but the big picture, the entirety. If I execute a thousand men for cowardice and ten thousand men fight harder as a result, then I have won a great victory. If I execute a thousand men and nine hundred fight harder, I have received a minor defeat. As such, next time I execute a thousand men, I must ensure it is effectively placed so as to motivate the most men possible. It is by sacrificing what is actually the minority to empower the majority that you win." - Commissar K59
So Commissars have always been one of my favorite
40k units and while I was working out today I had an epiphany: Why not have an army of Commissars?
Let me explain to you my idea:
Veterans would be Cadet Commissars. Imperial Guard sergeants would be a Commissar as well. I don't know how I could explain their loss of
BS compared to the Cadets but I figure if I added 2 points to the squad it wouldn't be a big deal if they were BS4. I would do this if playing with friends. Competition games, they'd just be BS3.
Commissars would of course still be Commissars.
I was thinking then of having a Lord Commissar, and then Iron Hand Straken as a counts-as Chaplain. The Chaplain and Lord Commissar would check for taint, instill religious values, and also make sure there is no dissent among the ranks.
Now I know in old fluff Chaplains used to make sure the Imperial Cult was upheld not only in Imperial marine chapters but also the Imperial Guard.
Anyway, as for the rest of the fluff, it would be mostly a Schola Progenium battlefield testing force. I may also include an Inquisitor ally from the Witch Hunters codex (for the short time they are going to be allies, that is!

)just for extra fun.
In short, as a testing force, they take potential Commissar recruits and they send them into battle. They will typically requisition Imperial Guard units in order for their Commissars to be tested, so there will be a variety of Imperial Guard units in the force. (Probably going to be mostly Valhallans and maybe whatever Imperial Guard I can find)
If anyone has any suggestions, I would very much appreciate it. It'll mostly be an infantry force though I plan to have a little bit of Chimera+Leman Russ support.
