One thing about the Claymore that hasn't been mentioned is how it got it's name. What could be a more appropriate name for a directional mine that cuts a wide swath out of the enemy, than being named after a rather large English sword that was also known for cutting a wide swath out of the enemy.
The Russian copies of the claymore and directional mine family are designated MON-50, MON-90, MON-100 and MON-200. The MON-100 and MON-200 are of a circular Miznay Shardin style design. The designation numbers in their names refers to the kill distance in meters that they are rated for. The shrapnel pieces used in the MON-200 are approximately 2 inch long sections of steel reinforcing bar as is used in concrete construction. MON-200 mines were used very effectively most recently against armored vehicles in Iraq and Afghanistan.
