The Enduring Freedom project is aiming to bring realistic combat simulation to the GEM 2 engine and is focused on the units involved in the initial coalition combat ops during Operation Anaconda in Afghanistan (Special Forces, 10th Mountain Div, and 101st Airborne). Conventional warfare will be presented as well. Project features and info can be located in the news section.
