Speaking of trenches: I want to do a three-tier trench line for a Bolt Action/Konflikt 47 table. I don't want vehicles to be entirely out of the game, so I'm considering having the trench network only cover half the table, the justification being that the ground turns rocky enough it can't be dug in, so this is the end of the line where it converts to a series of outposts instead. Do you guys think that's a good way to keep vehicles involved in the gameplay?

The other option is adding bridges over some of the trenches, which seems odd to me.
