We need a barracks as models. All building/structure should be either military grade tents or military looking building that you would find on a battlefield.
File format to export too *.FBX
Poly Count as low as possible... if the model was on a flash card you should be able to flash it up and some identify it right away. This is a game asset so we need the tris/poly count as low as it can be but still able to be identified fast.
Art style should be realistic but not to the point of it being boring. Also the project page and our wiki page has our art direction using reference from the game "Real War"
