@womble,
I might be wrong but I think 'Small City' is that rare thing, a totally flat CM map. On two occasions so far the Comment Commanders have lost vehicles to Shermans that were firing over adjacent high walls (Hetzer - turn 5 , halftrack - turn 11) . Happily, they got some revenge in turn 13 by turret-potting one of the 'Kilroys'.
@Pete Wenman,
Thanks.
