Part of my job as an Army Combat Engineer was Mine/Countermine operations. In other words laying, and clearing minefields, so I know a little bit about one of the most heinous weapons of war man has ever created. Land mines are not something to joke about. They kill and maim without prejudice. They do not care what color you are, they do not care if you are an adult, they do not care if you are a child, they do not care if you are male or female.
There are several types of mines. There are the M14 toe poppers—these are evil little shits. They are made of plastic and cannot be picked up on a mine detector, so these bastards are made to wound you—to take your foot off, to permanently maim you. It is a pressure mine; you step on it, it goes boom, you say good-bye to the body part that triggered it. It is not like the movies where you have time to hear the click and think about this poor life decision. It just goes boom.
Then, there is the M16 Bouncing Betty—now Betty is probably the most diabolical weapon ever created by man. There are many ways Betty can be set up: positive trip wires, negative trip wires (where she goes boom if you cut the wire), pressure, or movement. She does the most damage with a trip wire. You trip the wire, and she bounces out of the ground about waist high and rips you in two. Regardless of the way she goes boom, you will not survive a meeting with Betty. She will kill you.
The M18 Claymore: this bastard has a curved front and it even says "Front toward Enemy." It is normally used as a defensive mine around a perimeter and is electrically triggered; however, it can be used with trip wires. Set this bastard off and you won't live to tell about it, you will be full of steel shot.
Anti-tank mines, M6, M15, M21 (tilt-rod)—these mines are pressure mines, and the M21 also has a "tilt-rod." The rod moves and then it goes boom. It takes some weight to make these go boom—a person standing on it likely won't do it, but drive a car over one, and you go boom. These were made to take out tanks, so your car will be peeled open like an onion if your were to drive over one. There will be no remains to send home.
I have seen actual minefields in use. There was one right across from me at OP Alpha. I saw East German Pioneers (engineers) maintaining these minefields. I know what they can do—and anyone who suggests using a minefield to secure our border is a fucking fool. These weapons of war don't care about nationality, they just kill.
