I think all of that is in keeping with the realities of 19th century warfare in the ACW, so it's interesting to see it in action.
I'm not sure that was always the case. The fontal assaults against an entrenched foe a la Fredericksburg or Cold Harbor were obviously ill-advised, but Chancellorsville and Missionary Ridge were two notable offensive successes, not to mention the Peninsula campaign and Second Manassas.
I would also say that First Manassas and Antietam came within a hairs breadth of success for the Union Commanders.
