U.S. Army scientists have developed an advanced coating for fabrics that could make soldier uniforms much more effective at repelling water, oil and many other liquid chemicals.

This durable “omniphobic” coating is much more repellent than Quarpel – a water-repellent coating that has been used for the past 40 years, Army officials maintain.

“It’s omniphobic. That means it hates everything,” Quoc Truong, a physical scientist at the Natick Soldier Research, Development and Engineering Center, said in an Army press release.

Truong and other Army scientist developed the coating to ensure “minimal impact to Army fabrics’ original physical properties and performances, such as comfort, while providing added repellency to water, oil and toxic chemicals,” the release states.

The coating greatly reduces how often soldiers need to clean their clothes and enhances chem-bio protection, according to Army officials.

Uniforms treated with the coating then underwent field testing to assess field durability, performance and user acceptance.

IWI US, Inc. just announced the release of its expensive new IWI Tavor Tactical Combat Folding Knife.

This exclusive design is produced from the “finest CPM-154 steel and is set into a textured G-10 handle that aids in grip retention. It has all black stainless steel hardware with a black anodized aluminum back spacer, incorporating a silky smooth 16 ball bearing system that ensures a solid lock up and zero side-to-side play,” IWI US officials maintain.

Threaded-Barrel-e1413788286884

SilencerCo announced today it will offer a new line of threaded barrels for Glock and other popular pistols.

Rifle barrels can easily be threaded to accept a suppressor, but most pistols require the purchase of a threaded aftermarket barrel to take advantage of the benefits a silencer can offer.

“The only thing better than a normal pistol barrel is a threaded pistol barrel,” SilencerCo CEO Joshua Waldron said in a press release.  “All pistol silencers require one. We noticed a market need for high quality pistol barrels, and we stepped in to offer them.”

140428-A-KG432-116

U.S. Army scientists are trying to show how better-fitting body armor can improve a soldier’s performance.

Members of the Anthropology and Human Factors Teams at the Natick Soldier Research, Development and Engineering Center are conducting a range-of-motion and encumbered anthropometry study to better understand the link between fit and performance with the Improved Outer Tactical Vest Gen III.

“We have this belief that if the fit of the body armor is really good, then the performance is going to be maximized,” Dr. Hyeg joo Choi, the principal investigator for the study, said in an Oct. 9 Army press release. “So the question is how can we quantify a good fit so that soldiers’ performance is maximized?”

To help answer that question, Choi and her fellow researchers collected measurements from 23 soldiers at Natick, including 21 males and two females.

Ultra Lightweight Ballistic Bump Helmet-high res
3M is showing off its new Ultra Light Weight Ballistic Bump Helmet at AUSA 2014. Made by Ceradyne Inc., a 3M company, the ULW-BBH shell weighs 30 percent less than the closest alternative and is designed to help reduce fatigue while improving mobility, 3M officials maintain.

The helmet uses the latest ultra-high molecular weight polyethylene and is manufactured using a proprietary, seamless, ballistic molding technology. It provides blunt-impact protection equivalent to the Advanced Combat Helmet for operations in the air and water, and during ground transportation. It also meets a common ballistic standard against the NIJ-IIIA level of threat and “17 Grain FSP V50.”

“We put our engineering and advanced materials expertise to work to combine the capabilities of bump and ballistic helmets into one multiuse platform,” Cheryl Ingstad, 3M business manager, Advanced Ceramics Platform – Defense, said in an Oct. 13 release at the start of the 2014 Association of the United States Army’s Annual Meeting and Exposition.

Carl-Gustaf M4 (2)

Saab Defense unveiled the latest version of its Carl Gustaf 84mm weapon system today at AUSA 2014.

The new M4 Multipurpose Weapon System is about 30 percent lighter than the current M3 Multi-role Anti-armor Anti-tank Weapon System being used by special operators and conventional infantry in Afghanistan.

The M4 – known in the U.S. as M3A1 MAAWS, is the latest man-portable shoulder-launched recoilless rifle from Saab designed to provide users with flexible capability and help troops to remain agile in any scenario, Saab officials maintain.

The 75th Ranger Regiment and other special operations forces began using the M3 MAAWS in 1991. The U.S. Army began ordering the M3 for conventional infantry units to use in Afghanistan in 2011. The M3 weighs 22 pounds and measures 42 inches long. The breech-loading M3 can reach out and hit enemy targets up to 1,000 meters away.

The new M3A1 is significantly lighter and shorter than the M3. It weighs 15 pounds and measures 39 3/8 inches long. The weight savings comes from a titanium liner and carbon-fiber wrapping, Saab officials maintain.

Lithium TWS 3
U.S. Army equipment officials are encouraging units to use lithium AA batteries rather than the cheaper alkaline version to power thermal weapon sights and night vision gear.

The L91 lithium battery costs more but it lasts a lot longer than the alkaline alternative, according to Project Manager Soldier Sensors and Lasers officials.

Lithium batteries provide up to three times the operating time which will allow soldiers to carry less batteries on dismounted ops, said Joe Pearson, Logistics Management Division director for PM SSL.
