The U.S. Army's Pine Bluff Arsenal in Arkansas has ordered 29.5 metric tons of powdered sugar, prompting curiosity about its intended use.
According to Task & Purpose, the powdered sugar will be used to manufacture M18 and M83 smoke grenades and M8 smoke cartridges, which require a fuel that burns quickly and produces a large volume of smoke.
Powdered sugar is an excellent fuel for pyrotechnic mixtures, as it is mixed with a powerful oxidizer, such as potassium nitrate, to generate dense smoke rapidly when ignited.
Author's summary: The U.S. Army buys 30 tons of powdered sugar for smoke grenades.
