With RED VICTORY ,
since 3D is supported by the game natively ,
there is no need to use the 3D Terrain element that is discussed earlier in thread.
Just use JSGME to enable one or both Mods ,dont even need to use both ,since 3D Tanks and Infantry are already in the game.
My Mods are but alternatives ,that may make the game better for you.
However ,you may also like to use the excellent 2D/3D Mod as well.
Up to you.
Certainly worth a try I think.
