FRIES meaning in Governmental ?

Fast-roping, also known as Fast Rope Insertion Extraction System (FRIES), is a technique for descending a thick rope. It is useful for deploying troops from a helicopter in places where the helicopter itself cannot touch down. Fast roping is particularly useful for marines, who can use the technique to board ships at sea as well as to reach destinations on land. It is quicker than abseiling (rappelling), although more dangerous, particularly if the person is carrying a heavy load, because the rope is not attached to them with a descender. The person holds onto the rope with gloved hands and feet and slides down it. Several people can slide down the same rope simultaneously, provided that there is a gap of approximately 3 metres (9.8 ft) between them, so that each one has time to get out of the way when they reach the ground.
