The term "Army Arsenal" refers to a facility where military weapons, ammunition, and equipment are manufactured, stored, and maintained. These arsenals play a crucial role in ensuring that armed forces have the necessary resources to operate effectively. They may also conduct research and development to improve existing military technologies. In the United States, notable examples of Army arsenals include the Rock Island Arsenal and the Picatinny Arsenal. These facilities not only support the U.S. Army but also collaborate with other branches of the military and defense contractors to enhance national security capabilities.
