I agree, war is an awful thing, but sometimes necessary. Read some literature about people at war to gain an even deeper understanding. "We were solders once and Young" is a fantastic story of men at war. It involves the air-cav in Vietnam. Powerful stuff.
As for CM, the thing that struck me the first time I played it is the HIGH rate of casualties in the game. I kept asking myself if it were true or not. I know it's just a game, but if the KIA/WIA rates are as high as the game portrays the WWII battlefield was an extremely dangerous place to be.
I'm currently reading "Panzer Battles" by mellenthin. It's a somewhat tilted view of the Wehrmacht during WWII. The battle (from an operational perspective) descriptions are excellent, however there are some questionable, to downright racist, comments. Thankfully, the book is from a different era. It was written during the cold war in 56.
Finally, my father fought in Korea during 52-53. He recieved a Purple Heart and a bronze star. He doesn't like to talk about it. However, one time I was talking to him and I brought it up. He made one comment that hit me profoundly, "The War was a terrible waste of life".
