Wire Flashcards
What are barbed wire obstacles
reinforcing obstacles designed to impede, slow, or stop the movement of foot troops, and in some cases, tracked and wheeled vehicles
What are barbed wire entanglements
artificial obstacles designed to impede the movement of foot troops and, in some cases, tracked and wheeled vehicles.
The materials used in constructing barbed wire entanglements are relatively lightweight and inexpensive, considering the protection they afford. Barbed wire entanglements can be breached by fire but are built rapidly, repaired, and reinforced.
What are the main requirements when setting up and employing wire obstacles
• Must be under friendly observation, covered by fire, and where practical protected by anti-personnel mines, trip flares, and warning devices
• Concealed from enemy observation as far as practical by incorporating terrain features, ie reverse slopes, hedges, woods, and fence lines
• Should always be erected in irregular and non-geometrical traces
• Must be coordinated with other elements of the defense
• Should always be deployed in depth
– Belts
– Bands
– Zones
What is a belt
an entanglement one fence in depth.
What is a band
A band consists of two or more belts in depth, with no interval between them. The belts may be fences of the same type, or the band may be composed of two or more fences of different types.
What is a zone
A zone consists of two or more bands or belts in depth, with intervals between them.
What is the difference between fixed and portable entanglements
One is built in place and the other can be moved without complete disassembly
In zones, how are lanes and gaps arranged
Staggered in a zig zag pattern
How are entanglements classified
By use, depth, and whether they are fixed or portable
What are the three classifications of the use of entanglements
– Tactical
– Protective
– Supplementary
How are tactical entanglements placed
sited parallel to and along the friendly side of the final protective line
How are protective entanglements placed
located in places to prevent surprise assaults from points close to the defense area
How much buffer should there be from a protective entanglement and why
40-100 meters; In order to stay out of hand grenade distance
Where is supplementary wire placed
In front of the FEBA to break up the exact pattern of tactical wire
AND
To the rear of the FEBA it is used to connect and reinforce all the protective wire entanglements
Supplementary Wire = ?
(mean Perimeter) x (1.25) x (number of belts)
