I just joined a quads trench game on this map and after looking at how the map is laid out and the way it functions, it looks like this map will be impossible to win/play with this game style.
Unless I am not looking at this correctly, the only way to move through the map is via the Buggy Stop Junction. Well in trench we all know you can only advance when you attack, and cannot continue your attack from a region you just advanced. Because of this you cannot get to the other side of a Buggy stop since at the start of your next turn, it will revert to 1 neutral.
I feel like i have to be wrong about this, because I cannot believe the map passed the creation process with such a glaring problem for the Trench style of play.
