Barbed wire, also known as barb wire, is a type of steel fencing wire constructed with sharp edges or points arranged at intervals along the strands. Its primary use is the construction of inexpensive fences , and it is also used as a security measure atop walls surrounding property.
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.
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 .
A portcullis (from Old French porte coleice 'sliding gate') is a heavy, vertically closing gate typically found in medieval fortifications. [1] A portcullis gate is constructed of a latticed grille , made of wood or metal or both, which slides down grooves inset within each jamb of the gateway.
The outer fence was often located very close to the actual border. A further obstacle was added by placing short wooden anchor posts about 2 metres (6.6 ft) outwards from both fences. Barbed wire was strung between them to form a V-shape to hinder lateral movement by escapees. In some low-risk areas, only a single fence was installed. [20]
