A caltrop (also known as caltrap, galtrop, cheval trap, galthrap,[1] galtrap, calthrop, jackrock or crow's foot[2][3]) is an area denial weapon made up of usually four, but possibly more, sharp nails or spines arranged in such a manner that one of them always points upward from a stable base (for example, a tetrahedron). Historically, caltrops were part of defences that served to slow the advance of troops, especially horses, chariots, and war elephants, and were particularly effective against the soft feet of camels.[4] In modern times, caltrops are effective when used against wheeled vehicles with pneumatic tires.[5]

Today, it has reclaimed its old Greek name and reappeared as the tetrahedron, the bane of all vehicles running on pneumatic tires, and is used by both the military and police.
