Mines were used for the first time during the American Civil War in the United States (1861-1865). Antitank mines were later ameliorated and laid on the battlefields of the First World War. Mine clearing operations did not pose major problems with those visible and easy-to-detect Atk-mines. The reason why Anti-personnel mines have been conceived and systematically used on the Atk minefields during the Second World War was because such mines prevented the enemy from easy demining of the defense system.
