After more than 50 years of failed attempts, the U.S. military may be on the verge of ending its love affair with brass-cased ammunition, something that predates the Spanish-American War.
Traditional brass has dominated military small-arms ammo since U.S. troops stormed up San Juan Hill, Cuba, in 1898. The robust material performs well in the violent, super-heated space of weapon chambers during firing, but its sheer weight has always been a problem for infantrymen and logisticians alike.
Advancements in body armor, communications equipment and other tactical gear have weighed down U.S. combat troops in the Army and Marines, pushing individual loads well past 100 pounds and degrading service members' physical performance, U.S. military studies have shown.
Any cartridge loaded in brass case or shell.
