Abstract
A paint ball land mine comprising multiple PVC parts detonates and marks simulated casualties. The mine may be easily field stripped by hand. The mine forcibly detonates in response to physical contact without unbalancing, so that tilting forces that otherwise misaim the mine are avoided. A rigid cylindrical two-part base threadably receives a removable top. A sealed interior for holding colored fluid is defined therebetween. A gas cartridge housed vertically interiorly of the base may be detonated when forced into contact with a puncture pin. An integral, upwardly projecting dome mounts a detonator assembly, comprising a tubular plunger that slidably contacts the cartridge when fired. Escaping gases pressurize the mine interior, forcing colored liquid upwardly and outwardly through multiple discharge passageways that are angled acutely to aim fluid away from the center. A removable safety pin, temporarily engaging the plunger, may be “pulled” to “set” the mine.
