A covert taggant dispersing grenade includes: a shell, the covert taggant disposed in the shell; a dispersal apparatus operably associated with the covert taggant to disperse the covert taggant; and a propulsion section operably associated with the shell for propelling the shell through an atmosphere. A method for dispersing a taggant includes: launching a grenade containing a taggant over a target, the taggant being invisible in the spectrum of the human eye; and covertly dispensing the taggant over the target.

1. A method for dispersing a taggant in an atmosphere prior to an impact, comprising: launching, over a target, a grenade comprising: a pyrotechnic charge; anda bladder containing the taggant and disposed within a shell, the bladder separating the taggant from the pyrotechnic charge, the taggant being invisible to a human eye under ambient lighting conditions;receiving, prior to launching the grenade over the target, a selection of a particular fuse of a plurality of fuses located within the grenade, each fuse of the plurality of fuses having a different burn time; andactivating the pyrotechnic charge to cause overpressure of the taggant to burst the bladder in the atmosphere over the target, thereby dispersing the taggant over the target. 2. The method of claim 1, wherein the taggant fluoresces at ultraviolet wavelengths. 3. The method of claim 1, wherein a signature of the taggant decays over time. 4. The method of claim 1, wherein dispersing the taggant includes dispersing the taggant in a predetermined pattern. 5. The method of claim 1, wherein the shell further comprises: a nose cone comprising a plurality of apertures, wherein the taggant is forced through the plurality of apertures when the bladder bursts. 6. The method of claim 1, wherein the bladder comprises an elastomeric material. 7. A method for dispersing in an atmosphere a taggant over a target, comprising: receiving, prior to launching a dispersing grenade over the target, a selection of a particular fuse of a plurality of fuses located within the grenade, each fuse of the plurality of fuses having a different burn time;activating, by the particular fuse in the dispersing grenade launched into the atmosphere, a pyrotechnic charge;forcing, by the activation of the pyrotechnic charge, a piston toward a bladder positioned within a shell and containing the taggant; andover-pressuring, by the piston, the taggant to burst the bladder, thereby dispersing the taggant over the target. 8. The method of claim 7, further comprising forcing the taggant through a plurality of apertures in a nose cone of the dispersing grenade. 9. A method for dispersing in an atmosphere a taggant over a target, comprising: activating, in a dispersing grenade launched into the atmosphere, a pyrotechnic charge while the dispersing grenade is in the atmosphere;forcing, by the activation of the pyrotechnic charge, a piston toward a bladder positioned within a shell and containing the taggant; andover-pressuring, by the piston, the taggant to burst the bladder, thereby dispersing the taggant over the target. 10. The method of claim 9, wherein the taggant comprises a liquid. 11. The method of claim 9, wherein the taggant is configured to mark an individual. 12. The method of claim 10, wherein the taggant is not visible to an unaided human eye in ambient lighting conditions, and is configured to fluoresce when exposed to radiation of a predetermined wavelength.
