The last rules question from the Kubla Con tournament involves the mechanics of how a TuG pushes back a SuG. Below is my analysis - let me know if it's correct or not.
In the game, a SuG of mounted skirmishers (UG B) advanced to shoot at Rich Gagliasso's perfidious Romans (I know, an oxymoron. Oh, and they were UG A.) A TuG friendly to the SuG was close by like so:

I realized (so I thought) that if UG A advanced, it would push UG B into UG C, causing a KaB test on UG C as the mounted SuG burst through it, so I retreated UG B out of the way in the game. Later I brought up the point that Rich could have done terrible things to me, but was told, on no, nothing bad would have happened to me. I still don't quite believe it.
After the game I realized that if UG A advanced and contacted B, B could have done a runaway response (but without rolling for shooting) and all would have been fine - no burst throughs. Assuming, however that I let UG B get pushed back, I think that I have two choices how B is moved. The first is that it pivots to face off against UG A, ending up something like this:

This causes it to burst through UG C.
The other possibility is that it retains its orientation relative to the board, ending up 1 BW aways measured from the TuG to the point on the SuG that was first contacted it like so:

Again, UG B will burst through C.
However, what I was told was that UG B could simply be pushed back to its own rear like this:

But I don't think this last position is a legal pushback position as it doesn't conform to the two choices given on p. 111. The only choice that avoids a burst-through would be the run away response.

but agreed to pose the question on the forums. Does a routing unit that contacts the edge of a friendly unit but otherwise does not interpenetrate it cause a KaB test on it?
