  FIELDMAINTENANCE COMPANY
  9-44. The field maintenance company provides field-level maintenance support to the BCT. Field-level
  maintenance is on or near system maintenance, often using line replaceable unit and component replacement,
  in the owning unit, using tools and test equipment found in the unit. Field-level maintenance is not limited to
  remove and replace actions, but also allows for repair of components or end items on or near system.
  Field-level maintenance includes adjustment, alignment, service, applying approved field-level modification
  workorders as directed, fault/failure diagnoses, battle damage assessment, repair, and recovery.
  9-45. The field maintenance company provides lift capabilities, recovery of organic equipment, additional
  recovery support to supported units, and support of maintenance evacuation. Field-level maintenance is
  always repair and return to the user and includes maintenance actions performed by operators. The company
  provides limited maintenance support to the FSCs for low-density commodities such as communications,
  electronics, and armament equipment. The field maintenance company normally operates within the
  designated BSA.
  BRIGADE SUPPORT MEDICAL COMPANY
  9-46. The BSMC provides Role 1 (unit level medical care) and Role 2 (basic primary care) AHS support to
  all BCT units operating within the BCT area of operations as well as on an area basis to units outside the
  BCT. (See ATP 4-90.) The BSMC normally operates within the designated BSA.
  9-47. The BSMC evacuates, receives, triages, treats, and determines the disposition of patients based upon
  their medical condition. This includes tactical combat casualty care (TCCC), primary, and emergency
  treatment, including basic primary care. The BSMC provides an increased medical capability with the
  addition of x-ray, laboratory, combat operational stress control, and dental services and has limited inpatient
  bed space (20 cots) for holding patients up to 72 hours. The BSMC may be augmented with a forward surgical
  team (known as FST) or forward resuscitative and surgical team capability based upon mission requirements.
  Notes. TCCC is prehospital care provided in a tactical setting. TCCC (first responder capability)
  occurs during a combat mission and is the military counterpart to prehospital emergency medical
  treatment. TCCC is divided into three stages: care under fire, tactical field care, and tactical
  evacuation. (See FM 4-02 for additional information.)
  The mission of the FST is to provide a rapidly deployable urgent initial surgical service forward
  in a BCT or at echelons above brigade. The FST is a 20-Soldier team, which provides far forward
  surgical intervention to render nontransportable patients sufficiently stable to allow for medical
  evacuation to a Role 3 hospital. Surgery performed by the FST is resuscitative surgery—urgent
  initial surgery required to render a patient transportable for further evacuation to a medical
  treatment facility staffed and equipped to provide for the patient’s care. Patients remain with the
  FST until they recover from anesthesia and once stabilized, they are evacuatedas soon as possible.
  The FST is not a self-sustaining unit and must be deployed with or attached to a medical company
  or hospital for support.
  The mission of the forward resuscitative and surgical team is to provide a rapidly deployable
  damage control resuscitation process and damage control surgery forward in a BCT or at echelons
  above brigade. The forward resuscitative and surgical team is a 20-Soldier team, which provides
  far forward resuscitative surgical intervention to render nontransportable patients sufficiently
  stable to allow for medical evacuation to a Role 3 hospital. The forward resuscitative and surgical
  team provides the capability to perform resuscitative surgery (often referred to as damage control
  surgery) within the area of operations. Damage control resuscitation is a medical process that
  prevents or mitigates hypothermia, acidosis, and coagulopathy through combined treatment
  paradigms. Damage control surgery is rapid initial control of hemorrhage and contamination with
  surgical packing and temporary closure, followed by resuscitation in the intensive care unit and
  subsequent surgical exploration and definitive repair once normal physiology has been restored.
