A pyrotechnic spotting charge for training projectiles contains 30-50% zinc owder, 10-30% aluminum powder, 10-30% potassium nitrate or sodium nitrate, and 10-30% potassium perchlorate. The composition (a) is fast reacting and produces a large volume of white smoke visible at a great distance before the projectile buries itself in the ground and (b) is of low brisance and does not cause fragmentation of the projectile.

A smoke-producing composition which will produce a dense smoke in about 5 conds and continues to produce a visible cloud having a duration of about 10 minutes for military screening operations in the field. The composition has critical limits in proportions and particle size for effective and efficient use in the 81 mm mortar cartridge. The composition consists essentially of 75 to 90 parts red phosphorus of 10. +-. 5. mu. in size, 10 to 20 parts sodium nitrate of 30. +-. 15. mu. , and 4 to 10 parts of an epoxy binder. All parts being by weight.

This invention involves the incorporation of a relatively small quantity of irconium or other pyrophoric material in the high explosive composition of a munition, which provides incendiary, terrain illumination, spotting, and enhanced antipersonnel properties to the munition with little or no diminution of its explosive and fragmentation power.
