The outer case of the M18A1 Claymore mine is constructed of what material?

The outer case of the M18A1 Claymore mine is made of plastic. This design choice helps in a couple of critical ways. Firstly, the use of plastic allows for a lightweight structure, making it easier for soldiers to carry and deploy the mine in various environments. Secondly, plastic is resistant to corrosion, ensuring that the mine remains operational in different weather conditions and over time without significant degradation of its structure. Furthermore, the plastic housing is designed to help channel the explosive force forward, enhancing the mine's lethality while minimizing unintended collateral damage. This efficient design contributes to the mine's effectiveness on the battlefield.
