RANGER HANDBOOK

CHAPTER NINE
WATERBORNE OPERATIONS
9-1. GENERAL. The availability of ready-made bridges to a Ranger Patrol is not only
uncertain, but is highly unlikely. Therefore, it may become necessary for the patrol to employ
expedient stream crossing techniques. The leader will need to know various techniques in
order to make a successful stream crossing. The stream crossing team is designated and
instructed to prepare ropes and equipment, and to conduct team rehearsals. This team is
highly proficient in the mechanics of a stream crossing. This proficiency is gained by realistic
rehearsals, close inspections, organization and good control.
9-2. ORGANIZATION OF RIVER CROSSING TEAM.
(a) Number 1 man: Lead safety swimmer and far side lifeguard.
(b) Number 2 man: Rope puller, swims water obstacle pulling 150-foot rope, ties off rope on
far side anchor point.
(c) Number 3 man: Near side lifeguard is the last man to cross water obstacle.
(d) Number 4 man: Bridge Team Commander (BTC).
(e) Number 5 and 6 men: Rope Tighteners.
9-3. ONE ROPE BRIDGE (WET CROSSING).
(a) Special Equipment:
(1) Two snaplinks per piece of heavy equipment.
(2) Two snaplinks for every 120 feet of rope.
(3) One 14-foot utility rope per person.
(4) Two snaplinks per person.
(5) One waterproof bag per RATELO.
(6) Three B-7 life preservers.
(7) Three floatation work vests.
(8) Two 150-foot nylon ropes.
(b) Planning. A stream crossing annex is prepared in conjunction with the unit's operation
order. Special organization is accomplished at this time. For a platoon size patrol, a squad
is normally given the task of providing the bridge team, with the squad leader as the
Bridge Team Commander (see Chapter 2, page 2-6 e).
(c) Rehearsals and inspections:
(1) The stream crossing team always rehearses.
(2) Rehearse the entire stream crossing emphasizing:
(a) Security and actions on enemy contact.
(b) Actual construction of the rope bridge within EIGHT minutes on dry land.
(c) Individual preparation.
