A couple of questions arose from our last game. As far as we could tell the following are correct.
1.   If a TUG of cataphracts charges a Devastating Charger foot unit that has a short spear from the front. Does the infantry unit get the +1 for short spear, +1 for devastating charger, keeping the shatter possibility, and is standing to receive. The cataphract would get a +1 for devastating charger and +1 for long spear also having shatter possibilities.
2.   The above situation but the mounted unit is a charging lancer in good going. The infantry unit get the +1 for short spear, +0 for devastating charger, keeping the shatter possibility, and is standing to receive. The lancer would get a +2 for charging lancer also having shatter possibilities.
3.   Shatter and shove results apply to the adjacent fighting file even if the file is from a different TUG and is of a completely different type.

Assuming that the foot are close, that appears to be all correct to me.
