There are several synonyms for the term "ground-emplaced mine". Some of the most common synonyms include landmine, anti-personnel mine, foot trap and the claymore mine. These devices are typically explosive devices that are buried or hidden in the ground, designed to detonate when triggered by pressure from a person or vehicle. They are commonly used by militaries and guerilla groups to deter or harm enemy forces. While these devices can be devastating, they are also responsible for large numbers of civilian casualties. As a result, many governments have signed treaties to ban their use and work to clear them from affected areas.
