At it's core, Combat Mission: Shock Force is a military simulation depicting a hypothetical near-future conflict in Syria following a fundamentalist coup d’état. As in Afghanistan 2001, the radical new government's refusal to shut down major terrorist organizations and its' regional destabilizing effect, compel NATO Coalition forces into action.

Combat Mission: Shock Force focuses on the actions of the US Stryker Brigade Combat Teams (SBCT) and Heavy Brigade Combat Teams (HBCT) as they fight against Syrian Army Infantry, Mechanized and Armored units. Combat Mission: Shock Force also features Unconventional Threat forces such as terrorists, spies, suicide bombers, IED's and other deadly tools employed in the asymmetric warfare of the modern day.

Along with the standard Red vs. Blue engagements typified in most wargames, Combat Mission: Shock Force also allows players to fight Red vs. Red (Syria vs. Syria) and Blue vs. Blue (NATO vs. NATO) battles as well.
