  Direct Patient Care
  The mission set of direct patient care comprises of the medical functions of medical
  treatment (organic and area support) and hospitalization. Health service support
  includes the treatment of CBRN casualties. Although these medical functions are
  aligned with specific tasks, the execution of the individual functions are interrelated,
  interconnected, and independent and require close coordination and integration to
  facilitate effective and efficient provision of AHS support.

  care are provided by organic assets (medical platoons of maneuver forces and treatment teams assigned to

  the BCTs and EAB AHS units, this support is provided by the medical company (brigade support) and the
  medical company (area support). The area support function encompasses TCCC, routine sick call, emergency
  dental care, operational public health, and COSC support.
