The death automats - SM70 In the sixties the moved land mines detonated frequently by game and influences of the weather. Some areas were nearly mine free thereby. The escape succeeded to many citizens of the GDR into the west. The check plants should become still more insurmountable. An instruction of the boss of the border troops from 9 October 1970 regulated the testing of the fragmentation mine SM-70 in the border employment. 3.20 m were established a high putting metal fence, at which in three different heights the SM 70 was attached. At each SM 70 horizontal three wires were fastened; the upper and lower should prevent that birds released the SM 70. The middle one caused the release. Became if a wire splits or affects, by the explosion of the funnel 90 sharp edged steel fragments were fired. The fragments worked like Dumdum projectiles. „The optimal “range of fire amounted to 10 meters, but the projectiles could fly up to 120 meters. The existing release wire reacted to pressure and/or course. By a signal line an optical and acoustic announcement of the respective zone and the section was made in a Führungspunkt. So within a short time a group of alarms could reach the place and explore the explosion cause. In order to make the border again insurmountable, here a new SM 70 was installed. If that were not immediately possible, two posts stayed, in order to guard the place.
