Good day Cathartes,
Sorry for the delay in responding, wanted to gather some additional data first.
Re Ex 1: In the example nights posted the squads were about 50m apart, both squads were in buildings. My squad started as a full Bren Section, but got chewed up by the MG. A second squad was a rifle squad. Both had black circle on the MG42, and did not even suppress it at all. Playing as the Germans I have also noted that my MG42s are rarely suppressed. Even tanks seem to have little effect on them unless a lucky shot kills a team member.
I have also noted instances where when targeting with bren sections or riffle squads I get black target circles on German infantry squads that are in hedges, at relatively short distances (between 40m and 100m). I have even occasionally gotten black circles when they are in the open, but this is at longer ranges.
Re Ex 2: Agree re Panther front, but I have been taking side shots with Fireflys, Achilles and 17 pdr AT Guns, to no effect even under 100m. That said, I have recently managed to kill a Panther with an AVRE, though I targeted the ground beside the Panther vs the tank itself) and one Panther with a 17 pdr and one Tiger with a Firefly. Still, I would expect Fireflys and Achilles to have a better kill rate than I have experienced.
Couple of other things: M10s and Achilles often turn their turrets back and forth when aiming, especially when soft targets are around. I think this might be a conflict between the main gun and the rear firing 50cal. Changing the 50cal to an AA gun or 360 gun might resolves this.
Overall targeting is horrible. I have had shots from guns and tanks land 100m short, 50m wide and 100m past targets. The one that really get me is when they go past the target, over a 2, 3 or 4 storey building and land 5m to 10m on the other side of the building.
British flamethrower teams rarely use the FT. They switch to their rifles or pistols.
Gun crews (6 pdr and 17 pdr) often use their rifles instead of the gun to fire at soft targets (squads, hedges).
Playing as Germans, I lost a PzIV to a head on shot from a Tetrarchs. To best of my knowledge this is impossible. I rear shot sure, a side shot maybe, but not a front shot. As Brits I get green circles on PzIVs with Daimlers, though always the other side of buildings so have not tried taking one out yet.
Crocodiles are only available for purchase on morning of first day. After that the quantity available goes down to zero. Not sure if this was intentional.
