The Marine Corps has started fielding a new plate carrier vest that features a more streamlined cut and offers a 25% weight savings over the vests Marines currently wear.

The new Plate Carrier Generation III will go first to infantry and other combat-arms Marines and then to supporting units in a push to reach full operational capability by fiscal 2023, according to a recent Marine Corps Systems Command announcement.

The Corps selected Vertical Protective Apparel LLC in September 2018 to manufacture up to 225,886 of the lighter and better-fitting Plate Carrier Generation III in an effort to increase the performance of Marines on the battlefield.

"When you lighten the load, Marines can get to their destinations faster, and they're going to have more endurance, which increases their lethality," Lt. Col. Andrew Konicki, the program manager for Infantry Combat Equipment at Marine Corps Systems Command, said in a statement. "The PC Gen. III is important because it is nearly 25-percent lighter than the legacy technology."

Military.com reached out to Systems Command for the average weight of the PC Gen. III compared to the current plate carrier but did not receive an immediate response.

The Marine Corps conducted a study in 2016 using the prototype of the new plate carrier, which involved Marines wearing it while running through obstacle courses and taking a 15-kilometer hike, according to the release. The study results showed that Marines completed the courses faster and appeared better conditioned when wearing the newer plate carrier design, it states.

Program officials worked with industry to remove excess bulk from the legacy plate carrier to reduce weight and give Marines more freedom of movement for handling weapons.

The material of the PC Gen. III reduces water absorption, and designers shaved bulk from the vest by cutting out excess fabric from around the shoulders.

"The PC Gen. III improves the Marines' ability to shoot and move by eliminating excess bulk from the design, and cutting out the shoulders for a better rifle stock weld," Lt. Col. Bryan Leahy, who leads the Individual Armor Team at PM ICE, said in the release.

The PC Gen. III is better-fitting than the current vest. It fits closer to the body, increasing protection and decreasing the risk of injury because of improper fit, according to the release.

The Marine Corps also added more sizes, so nearly 15,000 more male and female Marines will be able to get a proper fit when wearing the system, it adds.

"I think there's a misconception that all females are small, and that's not always true," said Konicki. "We conducted a study that found the smallest Marine is actually male."
