Each Warrior has their own unique terrain that they have adapted to. In simulated battles, the two warriors have to use their own territory while crossing into the enemy's territory. Most territories shown in the simulation are similar but some are entirely different.
Season 3 showed many terrains in the sim; forrest, desert/tundra, mountain, open plains, jungle, indoor, hills, swamp and city streets.
Pirate vs Knight
The Knight fights in a light forrest similar to the forrests of Europe while the Pirate fights on a beach with a rowboat on the shore and his pirate ship in the background.
IRA vs Taliban
This fight is in a junkyard in a dry valley. The final IRA soldier and two taliban enter an RV and city bus and the same IRA soldier uses a car door against a Taliban. One taliban uses the narrow spaces of the cars to his advantage by planting a mine that an IRA soldier gets killed by. Another IRA soldier uses a flamethrower near an oil truck, which might had increaded the explosion that kills him.

US Army Rangers vs. North Korean Special Operations Force
This battle is the first to be set up in a specific geographic location, the Korean Peninsula along the coast of North Korea. This also makes it the first battle to be set in a location that gives one of the warriors an advantage over the other, since the NKSOF are fighting on their own turf.
