Case 1.
Imagine I have a line of Cv trying to contact an enemy line of Bd defending TF hat are 2 cm deep. Moving my Cv straight ahead 240 p I can contact their TF but not the Bd. Now imagine just half of the enemy line is defending TF and the other half is not. If I move ahead, what will happen with my element overlapping its friend in contact with an enemy TF? This overlapping element will be 2 cm away from its enemy but technically overlapping.
Ouch, good question.
Neil, the question isn't about undefended TF, but a situation where some troops in a line are protected by TF and some aren't, and where the advancing troops have the movement to contact the TF (and thus the troops behind it) but not the unprotected troops.
So the situation looks like this (crosses fingers):
C1C1C1C1
C2C2C2C2
TFTF
BdBdBdBd
The Cv group has moved from C1 to C2, and has contacted the TF. It's therefore in contact with the two left-most Bd elements. The question is, does the 3rd Cv element (the first one not to be in contact with the TF) provide an overlap for the 2nd Cv element?
In the absence of anything clarifying this exact situation, I'd make a ruling based on its appearance - the 3rd Cv element
would provide an overlap, as the situation is not one excluded by the dot points on overlaps (p 35), and is not covered by Storming Fortifications (p 42).
Case 2.
Same as case 1 but now all Bd elements can be contacted when moving 240 p straight ahead. Is my group "broken" as they contact enemy at different distances?
Double ouch. A second very good question.
And again, as the situation isn't covered by the rules, I'd make a ruling based on its appearance. In this case I'd say Yes, the group is broken. And, incidentally, I'd rule that you'd need two PIPs to make the move, as they're actually two moves.
