  devices to aid in assembly. Because assembly aids can attract the enemy’s attention, pathfinders must
  carefully avoid compromise.
  Electronic
  1-19. These include radios and homing devices that work by radio signal. Enemy direction-finding
  equipment detects electronic signals.
  Visual
  1-20. These simple-to-use aids allow positive identification of assembly areas. The enemy can also see
  them. To ensure understanding, pathfinders must closely coordinate the use of visual assembly aids. (See
  TM 9-1370-206-10, FM 21-60, and STANAGs 3117 and 3281.) Visual assembly aids include the
  following:
  Day
  1-21. Visual assembly aids that can be used during the day, which include—
  y Panels.
  y Smoke.
  y Armbands.
  Night
  1-22. Visual assembly aids that can be used during the night, which include—
  y Lanterns.
  y Flashlights.
  y Light beacons.
  y Strobe lights.
  y Chem-lights.
  y Pyrotechnics.
  Infrared
  1-23. Pathfinders can use infrared light sources as assembly aids, but if they do so, both the pathfinders
  and the pilots must use night vision devices (NVDs).
  MISCELLANEOUS
  1-24. Pathfinder equipment also includes—
  y Vehicles.
  y Binoculars.
  y Night vision devices.
  y Nonelectric demolition kits.
  y Wind-measurement equipment.
  y Parachutes.
  y Equipment for detecting CBRN.
  y Thermal sights.
