A Forward Operating Base (FOB) is a military facility that is established to support operations in a specific area, often close to the front lines. These bases provide essential services such as shelter, logistics, and medical support for troops. They are strategically located to enhance operational effectiveness and ensure quick response times during missions. FOBs can vary in size and complexity, ranging from small outposts to larger installations with advanced facilities. They are crucial for maintaining a military presence in a region and often serve as a hub for coordination with local forces and other military units, such as those from NATO or the United Nations.
