The Artillery Loop (also known as the harness loop or man-harness knot) is a knot used to create a stationary loop in a piece of rope. It was so named because of its use in the military. The running ends, A and B, would be tied to the ends of a barrel or field gun, and the loop, L, would be used as a grip or handhold so that the soldier could move the weapon. The loop could also be lengthened to create a shoulder harness. After prolonged firing, gun barrels get extremely hot, so these makeshift handles were a great help when weapons had to be quickly transported during battle. This loop knot was also useful because it is simple to tie, and you do not need to manipulate the running ends of the rope to tie it.
