If equipment is cached inland, follow normal caching procedures.

TC 18-01,
Special Forces Unconventional Warfare, for additional details on caching operations.


Which craft normally initiates the signal for exfiltration? Recovery team or recovery craft?

Recovery team.


Team infiltration swimming techniques are generally?

"on line" and "column"


Who informs all the divers of heading before entering the water?

The compass person.


What are the scout swimmers duties and responsibilities?

The scout
swimmers are employed to conduct a reconnaissance and secure the BLS prior to committing
the entire recovery team.
they must also locate an assembly area, look for suitable cache sites, and select
a location from which to signal the team. They must also meet a reception committee if one is


While the scout swimmers recon the beach how far will the team distance be?

About 500m or outside of small arms fire


Beach landing site signals are?

1. Safe Signal
2. Delay Signal
3. Abort Signal
4. Absence of Signal


The absence of signal precludes what?

Safe landing for the team.


What stroke do you use when you are getting close to BLS?



Is a quick release required if a swimmer is swimming a ruck?

yes, you need a quick release just incase it gets caught and/or sinks


What is the optimum weight ceiling for the F470 CRRC w/ and outboard motor (OBM)?

2,000 pounds


How should you approach the survivor in the CRRC?

Approach the survivor facing into the current or wind, whichever is the
stronger of the two.


What needs to take place for CRRC recovery by large vessels?

The CRRC must be prerigged with a bow line (Zodiac part number 2973) or a locally
manufactured line with a pulley is preferred to allow the boat to self-center while being towed;attach to the two D300 towing rings located on the bow. The two D300 rings are located just
above the water line on the bow. The lifting harness should also be installed to facilitate lifting
or lowering. Approach the larger vessel’s leeward side. The larger vessel should establish a 3-
to 5-knot troll. The larger vessel will deploy a painter’s line to attach to the bow line. The
forward motion of the two vessels will bring the CRRC alongside the larger vessel. Kill the
CRRC engine and raise it out of the water. A stern line will usually be attached to steady the
CRRC during lifting operations. A hook or davit will be lowered and should be attached to the
lifting harness. Transfer


CRRC raising into a larger vessel considerations are? General Considerations. To effectively raise and lower a CRRC in the water,
make sure the ship has ±3 knots of water speed for steerage. This also allows the CRRC an
escape in four directions. The CRRC comes alongside the ship and matches speeds and
checks for hazards and stability of the ship. The coxswain first off-loads any extra team
members on the Jacob’s ladder or some form of ascending device. When the coxswain
off-loads, the Nichols Zodiac raising device is also sent up. The ship’s crew then sends
down the Nichols device with a 30-foot rope attached. At this time, the coxswain then
deploys the sea anchor and matches speed with the crane shackle that is lowered to the
mean water line. This configuration allows the CRRC to come alongside the shackle
without getting under it. The Nichols device is then attached to the 12-point sling. The
coxswain will kill the engine, and then along with any remaining team members will
off-load the CRRC via the Jacob’s ladder or other type of ascending device.


Should you raise or lower CRRC w/Personnel?

WARNING: Do not raise or lower CRRC with personnel on board; CRRC floor and lifting
harness are not man rated.


When is it appropriate to wear a dry suit hood?

In water less than 70 degrees F, hoods should be a minimum
of 3mm thick to decrease heat loss and help prevent vertigo induced by having cold
water flood the ears.
