Actually, that's a great idea. I am curious how Smitty is going to tackle that problem. I would imagine he will get the basics done first, and from there go into bigger issues, such as workable naval mines and trenches, etc. I am at a standstill on trenches myself, we need an improvement like the trenches in civ 3. I f you can make a farm or a mine or a windmill, I am sure you can make an improvement look like a trench, with barbed wire, or make it look like a concrete bunker, for more elaborate trench works. Thing is you would have to make it take some punishment. You cannot have an old Taube come by and blow it to smithereens with one shot.
