text: Army Health System Overview
  1-5. The Army Medicine views threats from two perspectives: the general threat and the health threat.
  Although the Army Medicine’s primary concern is that of the health threat, the general threat must also be
  fully considered as it influences the—
  * Character, types, and severity of wounds and injuries to which our forces may be exposed.
  * Enemy’s ability and willingness to disrupt AHS operations and to respect the conditions of the
  Geneva Conventions in regards to the protection of AHS personnel while engaged in their
  humanitarian mission.
  HEALTH THREAT
  1-6. The health threat faced by deployed U.S. forces is depicted in Table 1-1. The health threat is a
  composite of ongoing or potential enemy actions; adverse environmental, occupational, and geographic and
  meteorological conditions; endemic and emerging diseases; and employment of chemical, biological,
  radiological, and nuclear (CBRN) weapons (to include weapons of mass destruction that have the potential
  to affect the short- or long-term health [including psychological impact] of personnel).
