text: Environmental and Terrain Considerations for Fire Support
  D-61. Maritime strike force package is a preplanned on-call package specifically designed to support
  maritime targeting and strikes. Maritime strike package is executed by a mission commander and consists of
  three elements:
  * Tactical C2.
  * Support element.
  * Strike.
  D-62. Critical components of an adversary ship are radars, missile launchers, guns, ammunition magazines,
  control rooms, engine rooms and hull. Upon assignment of the force package, rehearsal of concepts and battle
  drills should be executed to ensure roles, responsibilities, timing, and effects are sufficiently understood by
  all participants. When targeting adversary’s maritime forces, the most considered effects are:
  * Fire power kill (F-Kill).
  * Gun kill (G-Kill).
  * Mission kill (M-Kill).
  * Sink/seaworthiness kill.
  * Mission control kill.
  D-63. Target engagement authority in a maritime environment, should be delegated to a C2 node that has the
  highest situational awareness and the ability to expedite an integrated joint strike. For more information on
  joint FSCMs and maritime operations see JP 3-02, JP 3-09, and FM 3-0.
  SECTION III – MOUNTAIN OPERATIONS
  D-64. In combat operations, mountains generally are characterized by rugged, compartmented terrain; steep
  slopes; and few natural or man-made lines of communication. The weather spans the entire spectrum from
  extreme cold, with ice and snow, to extreme heat in some areas. Vegetation can vary from dense jungle to
  barren waste. Variability of weather over short periods of time and of vegetation from area to area
  significantly influences both maneuver and FS operations.
  MUNITIONS
  D-65. Munitions effects are affected by the environment and terrain. IPOE helps determine where and what
  munitions are most effective. Below are munitions considerations for mountainous terrain.
  * In snow:
   FA delivered mines may settle into the snow off vertical. At temperatures lower than -15° C,
  very little settling occurs.
   Variable time and time fuzes are most effective in most cases.
   HE - point detonating, HE-delay, and improved conventional munitions are ineffective
  because at least 40 percent of the effects are muted by the snow.
   The phosphorus in white phosphorus (referred to as WP) can burn undetected in snow for up
  to four days.
  * In rocky terrain:
  * HE-point detonating is very effective because it produces extra fragmentation from splintering
  rocks.
   Variable time and time fuzes are very effective because the burst covers a larger area than
  HE-point detonating on reverse slopes.
   FA mines are effective to deny the enemy the use of narrow defiles, valleys, roads, and usable
  terrain.
  * When smoke and illumination are used:
   Swirling winds make smoke employment very difficult to adjust and maintain.
   Close coordination is required with adjacent elements to ensure they are not obscured or that
  they are not highlighted.
