  TRAVELING
  2-18. Traveling is a movement technique used when speed is necessary and contact with enemy forces
  is not likely. All elements of the unit move simultaneously. Commanders or small-unit leaders are located
  where they can best control the situation. Trailing elements may move in parallel columns to shorten the
  column and reaction time. Figure 2-10 depicts the traveling movement technique.

  TRAVELING OVERWATCH
  2-19. Traveling overwatch is a movement technique used when contact with enemy forces is possible.
  A short distance, which varies with the terrain, separates the lead element and trailing element. The trailing
  element moves at variable speeds and may pause for short periods to overwatch the lead element. It controls
  its movement based on the terrain and the lead element. The rear element overwatches at such a distance that
  if enemy forces engage the lead element, it will not prevent the rear element from firing or moving to support
  the lead element. Figure 2-11 depicts this technique and shows how the overwatch can simultaneously occur
  at multiple echelons.
