The CH should be at 30FP down (at least) one because even if the leader is not in TEM terrain, FFNAM applies as a negative DRM to the effects DR [C3.71] (as would FFMO if applicable). If the leader had survived it would have been pinned because it wounded after having spent more than three MF [A17.2]. Also if the Tiger rolled snakeeyes, it had rate.
During the DFPh, using its ROF the Tiger would have DRM of -2 for point blank range & -1 for acquisition. If it is not BU (and assuming no other positive DRM apply) the Tiger gets a hit on an eleven and a critical on a six.

I rolled the aforementioned CH (not snake eyes, but rather < half the to hit number, with no rate) against Jon.
I admit overlooking the Pin result, and was not aware of SMC's not having to take the K/MC result.
Even if I were completely grounded on those subtle rules, I probably was too flummoxed from the leader surviving the CH.
The Tiger was ok as other results were favorable my way (e.g. PF shot from a dispersed smoke hex frying a British Churchill from a distance of two hexes).
Thanks to everyone for the commentary and pointing to the rules.
