  Timekeeper—The timekeeper keeps time during dead reckoning and aids in navigation. He
  provides flank security during movement.
  Navigator—The navigator tracks the team's movement on the chart and reads the GPS as needed.
  He notifies the coxswain of any changes in heading, and he provides flank security during
  movement.
  Observer—The observer(s) notifies the coxswain of any obstacles and provides frontal security
  during movement.
  PREPARATION OF PERSONNEL AND EQUIPMENT
  5-5. Each person dons a work vest, a life preserver, or both. He dons any additional equipment, such as
  LCE, over his vest. He slings his rifle over his life preserver, where it is readily available. Securely lashing
  radios, ammunition, and other bulk equipment to the boat prevents loss in case the boat capsizes. To lash
  equipment to the boat—
  • Secure a 5-foot section of 1-inch tubular nylon across the boat at the rear set of "D" rings.
  • Securely knot a 12-foot section of 1-inch tubular nylon to the front "D" ring. Place a loop about
  two feet from the other end of the rope. Using a slip knot, tie off this section to the
  5-foot section.
  • Attach a snaplink to the top of each rucksack frame and secure the rucksack to the
  equipment line.
  • Place the coxswain's rucksack at the rear of the boat. Route the snaplink through the loop at the
  rear of the equipment line. If the boat capsizes, the coxswain can release the knot, allowing the
  rucksacks to float free of the boat while he tries to right it.
  LAUNCHING OF BOAT
  5-6. When timing the launch, the coxswain observes surf conditions and considers wave intervals.
  When team members are about thigh deep in the water, the coxswain orders them to board by pairs. As
  soon as they board, they grab a paddle and help keep the boat perpendicular to the waves as the coxswain
  starts the motor. After the motor is running, the coxswain orders the rest of the team into the boat. To help
  avoid capsizing, the boat is kept perpendicular to the waves.
  BEACHING OF BOAT
  5-7. The coxswain observes the surf to see when to enter. To avoid capsizing, he has the team shift
  their weight to the rear of the boat before the boat enters the surf.
  5-8. As the boat enters the surf zone, all team members work to keep the boat perpendicular to the
  waves. The coxswain observes the surf and commands the team to vary speed as needed and to avoid
  plunging into breakers. He periodically looks seaward to observe the waves.
  5-9. When the boat reaches shallow water, the coxswain orders the team out of the boat in pairs, for
  example (short count), "Ones, out; twos, out" (Figure 5-2). On disembarking, each pair immediately grabs
  the boat handles and pulls the boat to the beach.
  5-10. The coxswain directs the team to empty the water from the boat and carry it to higher ground. He
  has two team members provide security.
  5-11. Once the team reaches an area suitable for caching the boat, they conceal it in a surface or
  subsurface cache, or, if required, they submerge the equipment.
