The effectiveness of any wire obstacle is greatly increased by planting anti-tank and blast antipersonnel mines in and around it. Additionally, connecting bounding anti-personnel mines (e.g. the PROM-1) to the obstacle with tripwires has the effect of booby-trapping the obstacle itself, hindering attempts to clear it.
The cheval de frise (plural: chevaux de frise [ʃə.vo də fʁiz], "Frisian horses") was a defensive obstacle, existing in a number of forms, principally as a static anti-cavalry obstacle but also quickly movable to close breaches. The term was also applied to underwater constructions used to prevent the passage of ships or other vessels on rivers.
Concertina wire or Dannert wire [1] is a type of barbed wire or razor wire that is formed in large coils which can be expanded like a concertina. In conjunction with plain barbed wire (and/or razor wire/tape ) and steel pickets , it is most often used to form military-style wire obstacles .
The Bangalore Blade is made from lightweight aluminium and is configured as a linear explosively formed projectile (EFP) array capable of cutting wire obstacles, which earlier Bangalore variants were incapable of breaching effectively. The improvements introduced with the Bangalore Blade give the charge a cutting action as well as a blasting ...
Czech hedgehogs deployed at the Stachelberg fortress in the Czech Republic. The Czech hedgehog (Czech: rozsocháč or ježek) is a static anti-tank obstacle defense made of metal angle beams or I-beams (that is, lengths with an L- or 𝐈-shaped cross section).
The anti-personnel obstacle breaching system (APOBS) is an explosive line charge system that allows safe breaching through complex antipersonnel obstacles, particularly fields of land mines. The APOBS is a joint DOD program for the U.S. Army and the United States Marine Corps .
The use of lines of barbed wire, razor wire, and other wire obstacles, in belts 15 m (49 ft) deep or more, is effective in stalling infantry travelling across the battlefield. Although the barbs or razors might cause minor injuries, the purpose was to entangle the limbs of enemy soldiers, forcing them to stop and methodically pull or work the ...
An abatis, abattis, or abbattis is a field fortification consisting of an obstacle formed (in the modern era) of the branches of trees laid in a row, with the sharpened tops directed outwards, towards the enemy. The trees are usually interlaced or tied with wire. Abatis are used alone or in combination with wire entanglements and other ...
