The problem with fences in hedgerows / stonewalls.

[A Canadian Cat]

There is a trick you can do to help mitigate that FOW limitation. Tanks and other vehicles can actually move through a gate without destroying the fence. I have not tried it with a wall yet - I keep forgetting. To do it they have to go through the centre of the gate and very close to straight through. So if you plot a way point near the gate centred on one side and another centred on the other side they can make it through without wrecking the gate section of the fence.

In some scenarios it can make a huge difference. I love it when a hack counter acts a limitation :)
