I've got a quick question about ambushes. My friend and I do LAN games quite often and found that fast units like Halftracks and Jeeps can speed through a (or more) ambushes without noticing.
An example would be yesterdays game. I was playing the German side and had Ski Infantry hidden in the woods to the left and right side of a road

. The had no supression and the visability was good.
The Russian halftrack was able to drive right past the two setups without as much as a hickup

. The track didn't see the Infantry, but I saw the halftrack before its move.
Does this have a higher reason I'm not understanding?
