In the United States Army, Medical Detachments (Forward Surgical), popularly known as Forward Surgical Teams (FST), are small, mobile surgical units first fielded during Operation Just Cause in December 1989. FSTs are utilized in a variety of ways, and can be fielded with support elements, including a Forward Support Medical Company (FSMC), Area Support Medical Company (ASMC), Brigade Medical Company also known as C-Med or in some cases stand alone (although The FST is not designed, staffed, or equipped for standalone operations or for conducting sick-call operations. Augmentation requirements are discussed in FM 4-02.25) to provide a surgical capability at Role 2 for those patients unable to survive MEDEVAC to Role 3 (hospital) care. Surgeons perform damage control surgery on combat casua.
