The document discusses troop leading procedures (TLP) for expeditionary engineering missions. It describes the eight steps of TLP as: 1) receive mission, 2) issue warning order, 3) make a tentative plan, 4) initiate movement, 5) conduct reconnaissance, 6) complete the plan, 7) issue operations order, and 8) supervise and refine the plan. Key aspects of TLP include developing a tentative plan using METT-TC analysis, issuing warning orders and operations orders in five-paragraph format, and continuously supervising preparations through rehearsals.
