Claymore mines are terrifying. Most commonly, though, they are used in large open areas and may be problematic if your home is not rural.

Claymores fire steel balls at a wide 60 degree angle. It's stated that they are guaranteed a kill at 50 meters but can still be dangerous out past 150 meters.

While claymores are often depicted as being laser or tripwire activated, they are most often activated using a clacker detonator held by an operator. They can be rigged to detonate via both electrical and mechanical means, so they can potentially be activated by a variety of methods.
