Re the "Mannschaftzug" this from Wikipedia (uncorrected Google translate from the German):
"As Mannschaftszug is called a method of crevasse rescue, so the rescue of a mountaineer from a crevasse.
When walking on a glacier with columns, it is advisable, in a roped party to go from 2 up to 6 people.
A crevasse rescue in Mannschaftszug by pulling the entire team on the rope. This is the Turned withdrawn without additional measures. This usually requires at least three, better four people on a rope.
However, it should be exercised with great caution, because of the climbers contained in the column can be pressed by the rescuers when pulling up from the column to the column border and serious injuries (thoracic injuries by compression on the column border).
In order to avoid further cutting the rope into the snow, a must on the column edge ice pick under the rope are laid. There must be the commands (the first in the rope after the casualty) a commander, the cable must be carried out smoothly and orderly. The commander has the pulling "pull rope by one meter" command or when the victim is dragged into the vicinity of the column edge "rope around half a meter pull" type."
