After years in the making, the Marine Corps has finally started fielding next-generation body armor to lighten the load for grunts in the field.

The new lightweight protective vest, known as the Plate Carrier Generation III, is designed to provide additional protection from shrapnel and other fragmentation for Marines, according to a statement from Marine Corps Systems Command.

More importantly, the new system is 25 percent lighter than the Corps’ existing plate carrier, providing a smaller footprint in terms of the load a grunt has to haul and in turn reducing fatigue and improving operational capability while maintaining a similar level of protection.
