The artillery loop is a knot with a loop on the bight for non-critical purposes. The artillery loop must have the loop loaded or it will slip and contract easily. It is an inferior knot to the alpine butterfly knot, possibly dangerously so, in that it can be yanked out of shape and turn into a running knot or noose.

Budworth states that this knot is often described as being best suited to take a load on only one of the ends, but reliable information on which end is difficult to find.
