  until they can be relieved. Units carefully plan for casualty evacuation in both COAs. An alternative solution
  is to plan and coordinate for sustainment from nearby units.
  RECONNAISSANCE METHODS
  12-82. Commanders consider the mission variables and the capabilities of their reconnaissance assets when
  deciding on a reconnaissance method. When possible, commanders typically employ combinations of these
  methods to increase the reconnaissance operation’s effectiveness. The reconnaissance methods include
  dismounted, mounted, aerial (manned and unmanned), and reconnaissance by fire.
  DISMOUNTED RECONNAISSANCE
  12-83. Dismounted reconnaissance is the most time-consuming method used by ground units. However, it
  permits the most detailed information collection about the enemy, terrain, civil considerations, and
  infrastructure. A commander considers using dismounted reconnaissance when—
  * Stealth is required, or security is the primary concern.
  * Time is available.
  * Detailed information is required.
  * The reconnaissance objective is a stationary threat, fixed site, or terrain feature.
  * Unit expects, or has made, enemy contact through visual and/or electromagnetic means.
  * Environment conditions favor dismounted reconnaissance or hinder mounted reconnaissance. (For
  example, terrain is muddy or swampy and is easier to traverse on foot.)
  * The terrain or threat preclude use of reconnaissance vehicles.
  * Vehicles are not available.
  * Terrain creates a visual dead space that prevents using optics or sensors.
  MOUNTED RECONNAISSANCE
  12-84. Mounted reconnaissance enables a more rapid tempo while increasing the potential compromise of
  reconnaissance operations. Mounted reconnaissance should take advantage of standoff capabilities provided
  by surveillance and weapon systems to observe and engage from greater ranges. A commander considers
  using mounted reconnaissance when—
  * Time is limited.
  * Distance to reconnaissance objective requires mounted movement.
  * Stealth and security are not primary concerns.
  * Detailed information is not required, or the mounted method affords the same scope as the
  dismounted method.
  * Environmental conditions permit this type of reconnaissance. (For example, the terrain is
  relatively flat and dry and tracked and wheeled vehicles can traverse with little difficulty.)
  * Enemy location is known.
  AERIAL RECONNAISSANCE
  12-85. Manned and unmanned aircraft system organizations are specifically equipped, organized, and
  trained to conduct reconnaissance. These capabilities are a key component of BCTs and above echelons
  information collection activities. Both UAS and manned aircraft possess the capability to operate
  independently or in conjunction with ground reconnaissance elements.
  12-86. Implementing airspace coordinating measures (ACMs) is a key requirement for the effective
  integration of aerial reconnaissance into all operations. At the BCT level and above units must ensure ACMs
  are planned and included in their unit airspace plans.
