Line of Fighting

[Francis Small]

I'm wondering if I'm interpreting the rules on the line of fighting correctly, because the way I'm reading them, the red TuG below is in a much better position than the blue TuG. Assume they are close foot and the brown is difficult terrain:



The rules state: "A file may choose whichever of its own fighting edge or its opponents fighting edge affects it least. You claim factors for this if the line of fighting of your opponent is even partly in such terrain."

I'm just confused about the meaning of that second sentence. If you choose your opponent's edge and it is partly in good going and partly in difficult, you are affected by the best terrain for that edge - but if you choose your own edge then you are affected by the worst terrain for that edge? In the above diagram that would mean that the red TuG can fight in good going because the blue edge is partly in good going and so affected by the terrain that affects it least, but the blue TuG is fighting in difficult going because the red TuG's edge is entirely in difficult, and it would otherwise choose the worst terrain on its own edge? That can't be right, can it?

Does the rule mean the equivalent of "A file may choose whichever of its own fighting edge or its opponents fighting edge affects it least. For the chosen edge, you affected by the worst terrain that edge is in."

If that's the case, then both blue and red are fighting in difficult terrain.

Indeed both blue and red are fighting in difficult terrain.  The rules for the situation where one is part within and on is full outside for instance.  If an age has any part within then it is affected.
