Viks - something to look out for. For Flying Corps Rowan used British trench maps to make their landscape; unfortunately they didn't realise that on British trench maps they showed the whole Gerrman trench sustem but only the British front line trenches, so that the map would be no use to the enemy if captured. Which resulted in the Flying Corps terrain having a full system of front line, second, third and suport trenches with communication trenches, and the Brits just having a single trench! You've probably taken this into account, but just in case...
