The Military Environment Creator Set includes everything you need for the base for a military render. The props are generic enough that it could be used for scenes from WWI to the present day.
If you want to set up a road block to catch suicide bombers, or have your hero winning the hearts and minds in the local village, or relaxing back at base camp with a cup of coffee, everything you need to get started in your scene is here. Trenches, barbed wire and sandbags for WWI scenes, foxholes and camouflage nets for WWII, anti-tank obstacles to stop those beasts in your Vietnam scene, or scouting out an Arab village, everything is possible with this model.
