Spotting issues (This IS crazy)
This is crazy.
I'm playing through kampfgruppe peiper, and a platoon of my infantry (dismounted) ran head long into a platoon of the enemy (mounted). Needless to say, it was a bloodbath. However that's not the surprising part.
The surprising part is when a sound contact (turned out to be a halftrack full of amerikanskis) RAN OVER a squad of veteran pioneers... who didn't notice... and kept running. Didn't even see it. The vehicle then came to a rest NOSE TO NOSE with one of my halftracks
There is a common misconception that in CM the distance at which enemy units can be spotted is also the maximum distance anything can be seen. In fact the former is usually a small fraction of the latter. The blue target line shows how far can be seen well enough to area fire. On a clear night this can be hundreds of meters while spotting distance may be a few dozen meters.
