It always seemed to me that the lack of horse transport for Germans was an odd omission in CMBO. Even as late as the Falaise Gap battles accounts mention the wreckage of horse transport.
But now that CMBB brings us even earlier in time I feel that omitting horse transport is not accurate. Perhaps in set-piece battles the horses would drop off their loads out of range of battle (esp if they are arty), but what about ambushes? It would be nice to have the option.
Looking at those fascinating pictures taken by Otto in the Ostfront (see other thread), it becomes clear that horses were a major form of transportation (esp comment that in '42 winter they didn't have proper snow transport and only horses were reliable).
Admittedly, no one wants to see game pix of Old Paint or the Black Stallion slaughtered and lying around, but if the game purports to be accurate then horse transport should at least be modeled.
