5-89: Simultaneous Relief

Previous: 5-88: Sequential Relief

5-89. Simultaneous relief is the fastest, but least secure, method. All outgoing elements are relieved at once, with the incoming unit usually occupying existing positions, including battle positions, and vehicle and individual fighting positions. The relief takes place in this general sequence:

  • Outgoing elements move to their alternate battle positions or vehicle and individual positions.
  • Incoming elements move along designated routes to the outgoing elements’ primary fighting positions.
  • The units complete the transfer of equipment and supplies.
  • Relieved elements move to the designated unit assembly area.
