👉 A poster weapon, also known as a poster or banner weapon, is a type of improvised explosive device (IED) commonly used by insurgents and terrorists. It typically involves a large, often improvised or scavenged, explosive device attached to a poster, banner, or other durable material. The device is usually designed to be thrown or detonated, causing significant damage and casualties upon impact. These weapons are favored for their simplicity, ease of concealment, and the psychological impact of their destructive potential, making them a versatile tool in asymmetric warfare.
