также кроме rope ladder
имеется и jacob's ladder Однако его связь с морской пехотой вряд ли поможет в гражданских текстах http://www.quantico.marines.mil/Portals/147/Docs/Range Management Branch/PubsInfo/3570/MCRP 3-11-4A.pdf JACOB'S LADDER OPERATIONS
CHAPTER 7
JACOB'S LADDER OPERATIONS
Like the SPIE system, Jacob's ladder operations
were developed as a means to rapidly extract per-
sonnel from an area that does not permit a heli-
copter landing. Unlike SPIE operations, Jacob's
ladder does not require that a special harness be
worn by personnel being extracted. Ladder opera-
tions are suitable for land, water, and waterborne
extractions. In water extractions, personnel
mount the ladder directly from the water. In
waterborne extractions, personnel mount the lad-
der from boats, barges, and oil platforms. This
chapter establishes the basic guidelines for
employing Jacob's ladder and training Marines in
the techniques needed to conduct a successful
operation using the Jacob's ladder.
