I am reading Canadian military Mines and Boobtraps, 1999 on Wikileaks right now. In a section about detecting minefields lists among other indicators these these signs :
f. empty containers of mines and components or explosiveIn a later section about dogs to detect mines it lists among other "unavoidable limitations".
packaging, wrapping and seals which may have been left
deliberately and booby trapped;
g. human and livestock corpses;
(3) inexplicable off day in a dog.The correct procedure for search individual mines in a minefield is laid out as.
"Ferro-magnetic objects should not be used to prod for mines, except in an operational emergency where it is deemed that the risk of personal injury due to accidental detonation is less than the operational risk."The manual lists how to arm , disarm and place the mine various mines Canada had in its inventory at the time. The claymore helpfully has “FRONT TOWARD ENEMY” written on the side that faces the enemy so that it always sited with “FRONT TOWARD ENEMY”.
