This will be interesting to see what industry comes up with to develop mortar rounds that are biodegradable after they are fired and impact in the ground:
In a famous photograph from 1967, a Vietnam War protester placed flowers into rifle barrels of National Guardsmen. That role could one day fall to tank commanders and mortarmen.
The U.S. Army recently sought proposals to make biodegradable 40 mm to 120 mm training rounds loaded with specialized indigenous seeds that, when grown, will eliminate ammunition debris and contaminants from ranges around the world.
The three-phase study will test the concept’s viability and look at the potential financial and environmental impact, according to Frank Misurelli, a spokesman for the U.S. Army’s Armament Research Development and Engineering Center at Picatinny Arsenal, N.J. If successful, the winning proposal would become a “Program of Record” and the rounds could make their way into America’s military training arsenal. [Stars & Stripes]
