A tactical obscurant device having an obscurant payload that comprises a plurality of powder particles radially pressed within a cavity of the obscurant device using a pulsed radial dynamic magnetic compaction process to provide a packing density of at least 40%, such that the obscurant payload has a greater packing density over traditional packing processes, which results in an increased obscurant cloud size upon detonation that is capable of screening in at least one range of the electromagnetic spectrum. The obscurant payload may be comprised of a single powder material, at least two layers of powder material, or may have a multi-layered packed structure using different types of powder materials that are packed concentrically for multispectral obscuration upon detonation. The pulsed radial dynamic compaction process not only allows for a greater packing density over traditional packing processes, but allows the plurality of powder particles to be disseminated as separate particles upon detonation for an increased cloud size for obscuration.
