Landmines Of Afghanistan

Metal detectors were first used for demining, after their invention by the Polish officer Józef Kosacki. His invention known as Polish mine detector Allies used to clear the German mine fields during the Second Battle of El Alamein when 500 units were shipped to Field Marshal Montgomery.
Whereas the placing and arming of mines is relatively inexpensive and simple, the process of detecting and removing them is typically expensive, slow, and dangerous. This is especially true of irregular warfare where mines were used on an ad hoc basis in unmarked areas. Anti-personnel mines are most difficult to find, due to their small size and the fact that many are made almost entirely of non-metallic materials specifically to escape detection.
Manual clearing remains the most effective technique for clearing mine fields, although hybrid techniques involving the use of animals and robots are being developed. Animals are desirable due to their strong sense of smell, which is more than capable of detecting a land mine. Animals like rats and dogs can also differentiate between other metal objects and land mines because they can be trained to detect the explosive agent itself.
