These were used by the Germans to defend beaches at Normandy and other coastal areas. Another caltrop-like defence during World War II was the massive steel, freestanding Czech hedgehog the works were designed as anti-tank obstacles, and could also damage landing craft and warships that came too close to shore. As dragon's teeth are immobile, the analogy with the caltrop is inexact. Large ones weighing over 1 tonne (1.1 tons) are still used defensively to deny access to wheeled vehicles, especially in camp areas. Much more common were concrete devices called dragon's teeth, which were designed to wedge into tank treads. Дuring the Second World War, large caltrop-shaped objects made from reinforced concrete were used as anti-tank devices, although it seems that these were rare. Their use in modern times targets the body and limbs of a falling victim by means of a pit or tripwire. These are sharpened sticks placed vertically in the ground. Punji sticks perform a similar role to caltrops. ' Tetrapods' (caltrop-shaped concrete structures) used as riprap along a seawall along the Marine Drive waterfront at Mumbai. Both types of makibishi could penetrate the thin soles of shoes, such as the waraji sandals, which were commonly worn in feudal Japan. Iron makibishi were called tetsubishi, while the makibishi made from the dried seed pod of the water caltrop, or water chestnut (genus Trapa), formed a natural type of makibashi called tennenbishi. Makibishi were sharp spiked objects that were used in feudal Japan to slow pursuers and also were used in the defence of samurai fortifications. The Japanese version of the caltrop is called makibishi. As with all military equipment designed for European wars, the caltrop's presence in Virginia must be considered in the light of possible attacks by the Spaniards as well as assaults from the Indians. The fact that only one has been found would seem to suggest that they were used little, if at all. There is no doubt that the most inscrutable Indian treading on a caltrop would be shocked into noisy comment. It amounts to a widely spread iron tripod about three inches long with another leg sticking vertically upward, so that however you throw it down, one spike always sticks up.

Undoubtedly the most unusual weapon or military device surviving from seventeenth-century Virginia is known as a caltrop, a single example of which has been found at Jamestown. A caltrop is a device composed of four spikes or points arranged so that in whatever manner it is thrown on the ground, it rests on three and presents the fourth upright.ДЄnother example of the use of caltrops was found in Jamestown, Virginia, in the United States:

The Roman soldiers rendered them useless chiefly by the following contrivance: at the instant the engagement began, they strewed the field of battle with caltrops, and the horses that drew the chariots, running full speed on them, were infallibly destroyed. And if one of the horses be either killed or wounded, it falls into the enemy's hands. As a chariot of this sort does not always meet with plain and level ground, the least obstruction stops it. The armed chariots used in war by Antiochus and Mithridates at first terrified the Romans, but they afterwards made a jest of them.

The late Roman writer Vegetius, referring in his work De re militari to scythed chariots, wrote: Caltrops were used in the Battle of Carrhae in 53 BC. The former term derives from the ancient Greek word tribolos meaning three spikes. The caltrop was called tribulus by the ancient Romans, or sometimes murex ferreus, the latter meaning 'jagged iron' (literally 'iron jagged thing'). Traditional and explosive caltrops from the Mongol Empire
