Survival skill FINDs terrain for Ambush; Tactics skill to best utilize it?

Hence why I'd allow it as a complimentary skill only. AK lets you know what's along the path the bad guys seem to be taking, so you can choose the best spot on the path, rather than having to pick the best you've seen 'so far' and potentially miss out on the perfect spot that's just up ahead. Naturalist would be similar - it lets you look at the land and be able to tell that there's some nice terrain coming up that you could use, so that helps your Tactics roll (assuming the AK/Naturalist user didn't mess up their roll and give bad advice, of course).
