Thanks for the report, it's always interesting to see a WWII game without armour!
I quite like the fire markers (not familiar with COC or what they represent) you are using, where are those from?
CoC is very much Platoon v Platoon with only occasional supporting tanks and the like - so armour's the exception in these games.
The fire markers represent shock - which has an attritional effect on units, making it harder to move, shoot them etc. and eventualy will cause them to be pinned or flee.
I think those ones are actually from the old GW Battlefleet Gothic game.
They're a bit more intrusive than we'd like, but they do the job until we can fettle something else.
