With respect to the American presence in Afghanistan, there are three types of facilities:
- Superbase - The only bases that fall into this category right now are Kandahar Airfield and Bagram Airfield in Afghanistan. They are built around supporting the regional military commands, and are logistical hubs for forces in the area. Soldiers stationed at these bases have access to the most comfortable living quarters, the most variety in food, shopping and socializing. For example, Kandahar Airfield has a weekly "Salsa Night" dance party near the TGI Friday's.
- Forward Operating Base (FOB) - Bigger than a COP, smaller than a superbase. A FOB can be austere and dangerous, but is more commonly provisioned with hot, varied meals, hot water for showers and laundry, as well as recreational facilities.
- Combat Outpost (COP) - A small base, usually housing between 40 and 150 soldiers, often in a particularly hostile area. Life at a COP is often austere and demanding, with every soldier responsible for both guard duty and patrolling
