Army’s next squad weapon will fire a never-before-seen ammo combination

INDIANAPOLIS ? The Army’s plan for a new squad automatic rifle will bring a type of ammunition combination, from bullet to casing, that’s never seen the battlefield.
Army Lt. Col. Andrew Lunoff, product manager for the service’s small caliber ammunition program, said that the round currently under consideration is the 6.8mm caliber.
Lunoff was speaking on a panel on intermediate caliber development at the annual National Defense Industrial Association Armaments Systems forum here.
The 6.8mm round is the offspring of a project formerly known as the Enhanced Rifle Cartridge Program that put together Special Operations Command, the Army Marksmanship Unit and Remington Arms to create an alternative to the 5.56mm round currently in use across the force.
That size ammo falls in the sweet spot the Army is looking for, with all the good characteristics of the heavier 7.62mm but with more lethality and accuracy — and coming in at an automatic 10 percent weight savings.

But work doesn’t end with the projectile, which hasn’t been officially named as the caliber but is the basis for much of current testing.
Lt. Col. Loyd Beal III, product manager for the Army’s crew served weapons program, said the requirements to lighten the load will mean not just a new projectile for increased lethality, but a new case to carry that bullet.
“The requirement is going to drive us to a new type of ammunition,” Beal said. “It’s going to have to be lighter. You can’t just go out and get a brass type, which pushes us to a polymer or some type of steel or something I don’t even know about yet.”
Beal added that while there has been a lot of promise in the development of Cased Telescope Ammunition, advances in other configurations give the Army a menu of options for developing the cartridge combination.

The intermediate caliber development is a simultaneous project with the Army’s plan to make the replacement for the Squad Automatic Weapon, known as the Next Generation Squad Automatic Rifle.
The NGSAR program, officials said, will inform not only a new machine gun, but it will soon follow with a new carbine for individual soldiers.

Army researchers are digesting the results of a two-year study that took a comprehensive look at how to build the rifle, ammunition and fire control system together, in order to build the next generation of small arms.

As the round is developed, Lunoff outlined the Army’s priorities.
First is a combat round, followed soon after by a blank round for training. Those are near-term goals.
Next, the service will need reduced range training rounds, tracer rounds, drill ammunition for weapon cycling, combat tracers and short range “paintball” type training rounds for close-quarter shooting.
SOCOM snipers will see barrel changes as early as next year to the commercially available 6.5mm round that will increase range, lethality, accuracy and reduce recoil.
Prototypes of the intermediate caliber for the NGSAR program are expected to be ready for testing by late 2019, early 2020, with the rifle being fielded to units by 2021, Beal said.

Army Tests Mechanical 'Third Arm' to Ease Weapon Weight

Army Research Lab engineers released a video recently showing a soldier running, diving and handling weapons attached to a prototype mechanical arm designed to help reduce the felt weight of carbines and machine guns.
The "third arm" is essentially a multi-joint, stabilizing appendage that attaches to the weapon and the soldier's waist belt to take the weight off the service member's arms and distribute it more evenly on the body, Dan Baechle, ARL mechanical engineer, said in a recent Army press release.
"It can help stabilize the weapon and take the load off of their arms," Baechle said. "It's made from composite materials to make it as light as possible but also to ensure the range of motion that soldiers need," he said.
During a recent test, a soldier wore the four-pound third arm while aggressively moving with an M4-style weapon at the Military Operations in Urban Terrain site at Aberdeen Proving Ground, Maryland.
The device also works well with light and medium machine guns, Baechle said.
"We've actually tested it with the M249 and M240B machines guns," he said. "The M240B weighs 27 pounds, and we were able to show that you can take the weight of that weapon completely off of the soldiers' arms."
Army engineers have improved the device from earlier prototypes after soldiers complained that they get into a prone position while wearing the device, the release states.
ARL conducted a pilot study in 2017 that showed the device can improve marksmanship in addition to reducing arm fatigue.
"We're using that small study to motivate a larger study this year with more soldiers taking a look at dynamic shooting scenarios," Baechle said.
"We get comments from soldiers who tell us different things about the way it feels on their body ... about the way it redistributes the load," he said. "Some like it; some give us tips about the ways it could be improved. And we're using that input to improve the device and improve the design so that it not only works well, but it also feels good."
No os riáis. Parece una tontería o un invento del TBO,
