I just finished reading Landscape Turned Red (which I really recommend if you are interested in the battle) about the battle of Antietam and there is a lot of factors in the real battle compared to the few that are in the game. For example green units on the Union side when facing veterans on the Confederate side broke almost the first time they were fired upon. Also the size of the new regiments of the 12th Corps caused some of the confederates to retreat out of positions they were holding (because they were large enough to look like brigades). Then you had regimental and company commanders either walking off the field or being killed causing new regiments to have issues getting in the correct formations (also they could not hear orders in all of the firing and they weren't experienced in drill). Friendly fire or not firing due to confusion was also a factor which is not in the game. Some units fought hard too, like the 12th Mass. took 67% casualties (32 out of 334 were left although stragglers came in later) along with the Louisiana Tigers which took 61%. Of course there were a lot more factors in real life but the AI in the game likes to stay and fight a lot longer and more reliably I think than they actually did in real life in a lot of cases. Plus if you are TCing them and making them stay past the point they would break there would be a lot more casualties too. Are there more factors in a unit breaking besides just %casualties?
One thing I really don't like about the game is the amount of hand-to-hand combat that occurs. If you want to add a lot of casualties to the numbers get into hand-to-hand (you can watch the numbers rise quickly when observing a unit in hand-to-hand). I've also never seen a unit that is charging break due to fire even if the defending unit is in the best cover possible and at full strength so there really is not a way to stop a charging unit if you are defending. My units are constantly getting into hand-to-hand combat...maybe I am doing something wrong.

All that to say that I think the casualties at least in the historical scenarios are ok in my opinion (they can vary though different times they are played).


Those are my thoughts...any corrections on how the game works would be great!
