Mines are explosive devices designed to detonate when triggered by pressure, proximity, or remote control. They are often buried underground or placed on the surface, making them difficult to detect. Mines can be used in military operations to protect areas or disrupt enemy movements. There are various types of mines, including landmines and sea mines. Landmines are typically used on land, while sea mines are deployed in water to damage ships. Both types can remain dangerous long after conflicts end, posing risks to civilians and hindering post-war recovery efforts.
