Abstract
A cartridge incorporating a projectile assembly, the projectile assembly having a base, mid body component housing a marking powder and metallic nose cap. The projectile's mid-body component houses liquids in a cylindrical compartment, where set-back and rotation induce chemical mixing, and in flight allowing for a chemical reaction, and at impact the projectile undergoes wall failure in the mid body, resulting from shear and residual rotational momentum, the actions in combination releasing and expelling marking materials, the ejection suspended signature producing materials, including liquid, powdered metals or fine particles released into the atmosphere emit and reflect light, the signature materials producing an observable signature at the projectile's impact location.
