text: Passage of Lines
  simultaneously. Passing forces’ plans address necessary branches and sequels in case enemy forces attack
  them during the execution of their passages to prevent degrading friendly maneuver.
  16-18. The passage of lines requires effective communication between passing and stationary forces. Units
  build redundancy of communication signals and means into their passage plans. They also designate contact
  points to ensure effective communication between these forces at the lowest possible tactical level.
  MOVEMENT AND MANEUVER
  16-19. The stationary unit identifies multiple routes through its assigned area. The passing unit begins
  reconnaissance of these routes as soon as possible. The stationary unit physically shows all obstacles, routes,
  and gaps through them to the passing unit. It provides guides for the passing unit—especially through
  obstacles—and occupies contact points and passage points. The passing unit begins to reconnoiter its routes
  to the established contact points with the stationary unit’s troops. The stationary unit establishes a security
  area in which responsibility transitions from the stationary force to the moving force. Normally, a BHL
  designates the forward edge of this area. The BHL is within direct fire range and observed indirect fire range
  of the stationary force.
  16-20. Passing unit commanders prefer to perform their passages through gaps in stationary unit positions
  rather than through lanes or routes that traverse those positions. This reduces the vulnerability of both passing
  and stationary units resulting from concentrating systems when units pass directly through the positions of
  other units. It also avoids the danger associated with concentrating passing units into passage lanes.
  16-21. Table 16-1 depicts the minimum number of passage lanes a BCT requires to execute a passage of
  lines. The routes and lanes should provide cover, concealment, and rapid movement of the passing force.
  Units may designate alternative routes and lanes for CBRN-contaminated elements of the moving force.
  These lanes disrupt the combat capability of the stationary unit to the minimal possible amount. If the terrain
  and enemy situation allow, units seek additional lanes to speed the process.

  In any passage of lines, a BCT needs at least one additional
  lane for its tactical vehicles
  16-22. Passing units normally have priority of route use to and within stationary unit assigned areas.
  Clearing and maintaining passage routes up to the BHL are the responsibility of the stationary force.
  Stationary forces provide passing forces with obstacle overlays. Passing units prepare to help maintain these
  routes, and they position their engineer equipment accordingly. Stationary units control traffic within their
  assigned areas until passing units assume control. Passing units augment the traffic control capabilities of
  stationary units as required during the passage.
  INTELLIGENCE
  16-23. Prior to a passage of lines, the stationary unit’s intelligence staff must exchange all intelligence
  products and databases with the intelligence staff of the passing force. This intelligence includes known and
  suspected enemy locations, enemy unit strengths, and enemy activity focusing on the previous 72 hours.
  16-24. In a forward passage of lines information collection assets are primarily tasked to support offensive
  operations following passage of lines completion. In a rearward passage of lines information collection assets
  are primarily tasked to support defensive operations following passage of lines completion.
  FIRES
  16-25. Generally, the stationary unit commander controls the allocation of firing positions until the
  execution of the BHL. The fires cells of the stationary and the passing units agree on the allocation of firing
  positions. These positions are far enough forward to support the performance of the passage without having
