here my issues:
Apparently when you are charge on the flank or rear you haven't the move to face your opponent or has I missed something?
In the same way what's happen when a TUG is charged on the flank on the rear base lose his base and he is already in melée with another TUG frontally ?
Same situation but with no opponent frontally.
1) There is indeed no way to turn facing the opponent that caught you on the flank except by M9. It speed up the game .
2) one dead base and the survivor engaged to the front will fight to the front .
3 ) the front base dies as the contacted base has to remain where it is . You may not break contact .
