👉 A trace weapon is a type of improvised explosive device (IED) that relies on the residual heat or chemical reaction of a previously detonated explosive to ignite a secondary explosive charge, often a plastic or fiber-based material. This secondary charge is typically designed to be highly sensitive and can be triggered by friction, pressure, or heat, making it easy to deploy without the need for complex equipment. The term "trace" refers to the small, often overlooked, trace of explosive residue left behind after the initial blast, which can be used to activate the secondary charge. These weapons are favored for their simplicity, low cost, and ability to be concealed or carried easily, making them a significant threat in asymmetric warfare scenarios.
