Army round triggers problems in Marine M27 auto rifle

Preliminary results of an Army test to see how the service's M855A1 5.56mm round performs in Marine Corps weapons show that the enhanced performance round causes reliability and durability problems in the Marine M27 Infantry Automatic Rifle, service officials say.


The Marine Corps in March added the M27 and the M16A4 rifles to the Army's ongoing testing of M855A1 Enhanced Performance Round at Aberdeen Proving Ground in Maryland after lawmakers questioned why the Army and the Marines use two different types of 5.56mm ammunition.

"One of the reasons we were doing that test was because of congressional language from last year that said 'you two services need to look at getting to a common round,' so we heard Congress loud and clear last year," Col. Michael Manning, program manager for the Marine Corps Infantry Weapon Systems, told Military.com in a Dec. 15 Interview.

Lawmakers again expressed concern this year in the final joint version of the Fiscal 2017 National Defense Appropriations Act, which includes a provision requiring the secretary of defense to submit a report to the House and Senate Armed Services Committees explaining why the two services are using different types of 5.56 mm ammunition.

Congress has approved the provision, but the bill is awaiting President Barack Obama's signature. The report must be submitted within 180 days after enactment of the legislation, which includes the entire defense budget for the coming year.

If the secretary of defense does not determine that an "emergency" requires the Army and Marine Corps to use the two different types of rifle ammo, they must begin using a common 5.56mm round within a year after the bill is passed, it states.

"The 2017 NDAA language doesn't surprise us; we kind of figured they were going to say that," Manning said.

Lead-free round

The Army replaced the Cold War-era M855 5.56mm round in 2010 with its new M855A1 EPR, the result of more than a decade of work to develop a lead-free round.

The M855A1 features a steel penetrator on top of a solid copper slug, making it is more dependable than the current M855, Army officials have said. It delivers consistent performance at all distances and penetrates 3/8s-inch-thick steel at ranges approaching 400 meters, tripling the performance of the M855, Army officials maintain.

The Marine Corps still uses the M855 but since 2009 has also relied heavily upon the MK 318, a 5.56mm round that's popular in the special operations community.

The Army's M855A1 test, which involves the service's M4 and M4A1 carbines and the Marine M16A4 and M27, is still ongoing and Marine officials are expecting a final test report in the April-May 2017 timeframe, Manning said.

Preliminary findings of the test show that the Army's M855A1 round meets all the requirements for a 5.56mm general purpose round in Army weapon systems, "but does not meet the system reliability requirement when fired from the USMC M27 Infantry Automatic Rifle," Army spokesman Lt. Col. Jesse Stalder said in a Dec. 16 email.

The Marine Corps began fielding the M27 in 2010 to replace the M249 squad automatic weapon in infantry squads.

The M27, made by Heckler & Koch, is a version of the German gun-maker's HK 416, an M4-style weapon that used a piston gas system instead of the direct gas impingement system found on the M4 and M16A4.

The Marines like it so much that the service is considering making it the next service rifle for infantry battalions in the Corps.

"In testing the Army states there was a reliability issue; that is true," Chris Woodburn, deputy branch chief for the Marine Corps' Maneuver Branch that deals with requirements, told Military.com in a Dec. 20 telephone interview.

Reliability refers to mean rounds between stoppages, Woodburn said.

"In this case, it appears the stoppages that we were seeing were primarily magazine-related in terms of how the magazine was feeding the round into the weapon," he said. "We don't know that for sure, but it looks that way."

New magazine

After further testing, Woodburn said the Marines have found a solution in the Magpul PMAG, a highly-reliable polymer magazine that has seen extensive combat use in Iraq and Afghanistan.

"It appears we have found a magazine that takes care of the reliability issues," Woodburn said.

Marine Corps Systems Command on Monday released a message which authorizes the PMAG magazine for use in the M27, the M16A4 and M4 carbines, Woodburn said.

"The reason they did that is because when Marines are deploying forward, they are sometimes receiving M855A1, and we need to ensure they have the ability to shoot that round," Woodburn said.

"In terms of the cause analysis and failure analysis, that has not been done, but what we do know is that the PMAG works," he said.

Preliminary tests also show that the M855A1 also causes durability problems in the M27, Woodburn said.

"Where it still appears that we still have an issue with it is it appears to degrade the durability," Woodburn said. "Durability is mean rounds between essential function failures, so you are talking bolt-part failures, barrel failures and the like.

"It is a hotter round and we think, that may be contributing to it, but we won't know for sure until the testing is complete," he said.

Previous setback

In 2008, the Marine Corps came out with a requirement for a new 5.56mm round that would penetrate battlefield barriers such as car windshields with our losing performance better than the older M855 round, Marine officials maintain.

The service had planned to field an earlier version of the Army's M855A1 until the program suffered a major setback in August 2009, when testing revealed that the earlier, bismuth-tin slug design proved to be sensitive to heat which affected the trajectory or intended flight path.

The Army quickly redesigned the M855A1 with its current solid copper slug, but the setback prompted Marine officials to stay with the current M855 round as well as start using the MK 318 Special Operations Science and Technology, or SOST, round developed by U.S. Special Operations Command instead.

The MK 318 bullet weighs 62 grains and has a lead core with a solid copper shank. It uses an open-tip match round design common with sniper ammunition. It stays on target through windshields and car doors better than conventional M855 ammo, Marine officials maintain.

The MK 318 and the Army's M855A1 "were developed years ago; they both were developed for a specific requirement capability separate and aside from each other," Manning said. "The bottom line is both of these rounds are very good rounds."

Both the Army and the Marine Corps "would like to get to a common round," Manning added.

The Army, however, maintains that it is "committed to the M855A1" round and so far has produced more than one billion rounds of the ammunition, Stalder said.

"It provides vastly superior performance across each target set at an extremely affordable cost and eliminates up to 2,000 tons of lead that would otherwise be deposited annually onto our training bases," Stalder said. "More than 1.6B rounds have been produced and reports on combat effectiveness have been overwhelmingly positive."

History

This pilot shot down an enemy fighter at Pearl Harbor in his pajamas

Comfort is important when doing a hard job. If it's hot on the work site, it's important to stay cool. If it's hazardous, proper protection needs to be worn. And comfort is apparently key when the Japanese sneak attack the Navy. Just ask Lt. Phil Rasmussen, who was one of four pilots who managed to get off the ground to fight the Japanese in the air.

Rasmussen, like many other American GIs in Hawaii that day, was still asleep when the Japanese launched the attack at 0755. The Army Air Forces 2nd Lieutenant was still groggy and in his pajamas when the attacking wave of enemy fighters swarmed Wheeler Field and destroyed many of the Army's aircraft on the ground.

Damaged aircraft on Hickam Field, Hawaii, after the surprise Japanese attack on Pearl Harbor.

There were still a number of outdated Curtiss P-36A Hawk fighters that were relatively untouched by the attack. Lieutenant Rasmussen strapped on a .45 pistol and ran out to the flightline, still in his pajamas, determined to meet the sucker-punching Japanese onslaught.

By the time the attack ended, Wheeler and Hickam Fields were both devastated. Bellows Field also took a lot of damage, its living quarters, mess halls, and chapels strafed by Japanese Zeros. American troops threw back everything they could muster – from anti-aircraft guns to their sidearms. But Rasmussen and a handful of other daring American pilots managed to get in the air, ready to take the fight right back to Japan in the Hawks if they had to. They took off under fire, but were still airborne.

Pearl Harbor pilots Harry Brown, Phil Rasmussen, Ken Taylor, George Welch, and Lewis Sanders.

They made it as far as Kaneohe Bay.

The four brave pilots were led by radio to Kaneohe, where they engaged 11 enemy fighters in a vicious dogfight. Even in his obsolete old fighter, Rasmussen proved that technology is no match for good ol' martial skills and courage under fire. He managed to shoot down one of the 11, but was double-teamed by two attacking Zeros.

Gunfire and 20mm shells shattered his canopy, destroyed his radio, and took out his hydraulic lines and rudder cables. He was forced out of the fighting, escaping into nearby clouds and making his way back to Wheeler Field. When he landed, he did it without brakes, a rudder, or a tailwheel.

There were 500 bullet holes in the P-36A's fuselage.

Skillz.

Lieutenant Rasmussen earned the Silver Star for his boldness and would survive the war, getting his second kill in 1943. He retired from the U.S. Air Force in 1965, but will live on in the Museum of the United States Air Force, forever immortalized as he hops into an outdated aircraft in his pajamas.

This Microsoft training fast tracks veterans into sweet tech careers

Solaire Brown (formerly Sanderson) was a happy, gung-ho Marine sergeant deployed in Afghanistan when she realized her military career was about to change. She was tasked with finding the right fit for her post-military life – and she knew she wanted to be prepared.

Injuries sustained during mine-resistant vehicle training had led to surgeries and functional recovery and it became clear Brown would no longer be able to operate at the level she expected of herself as a Marine.

Like many of the 200,000 service members exiting the military each year, Brown knew her military training could make her a valuable asset as an employee, but she was unsure of how her skills might specifically translate to employment in the civilian world.

Enter Microsoft Software & Systems Academy (MSSA), a program Microsoft started in 2013 to provide transitioning service members and veterans with critical career skills required for today's growing technology industry.

5 of the dumbest reasons people went to war

"War is a male activity. Organized fighting and killing by groups of women against other groups of women has simply not existed at any point in human history."

That's a powerful observation from evolutionary social psychologist Frank T. McAndrew Ph.D., whose writings on the psychology of going to war propose that men evolved to be more aggressive in order to compete for female mates.

How to get your own free 'Space Force' ringtone

If you're in the military or are a veteran and haven't heard about the Space Force yet, it's time to climb out from under that rock you've been living in. There's a sixth branch of the U.S. military now, and it's going to be a department of the Air Force.

The men's department.

Although the Air Force has released very limited guidance on what the new branch will do, how it will roll out, or basically anything at all except that it's called the 'Space Force' and will exist one day, the excitement the idea of a space force brings the military community is palpable.

Judged solely by the sheer volume of Space Force memes.

5 ways marksmanship simulations can improve your fire teams

The fire team is the most important unit of the Marine Corps' infantry. The Corps is always looking for new ways to make its fire teams more effective on the battlefield. From equipment upgrades to weapon replacements, there's always room for improvement. But one thing they have yet to figure out is what Marines at the lowest levels can do during their free time. Well, why not reserve some time at the Indoor Simulated Marksmanship Trainer?

At the bottom of the Marine Corps task organization is the four-person fire team and they are, by far, the most critical asset in the entire hierarchy. The more lethal each individual team, the more lethal the unit as a whole and the ISMIT gives troops the opportunity to practice their shooting skills without firing real bullets on a live range. It's like playing Nintendo Duck Hunt with military guns and honestly, it puts a lot of current virtual reality gaming to shame with its fun factor.

But beneath that, there's a deeper level of training value that can make a unit much more effective and especially more lethal, given the right prompt and simulation.

Here are some ways the ISMIT can improve your unit at the fire team level:

6 operators from Rainbow Six that would be awesome in real life

Tom Clancy's Rainbow Six Siege is one of the most entertaining games online for the military community. It takes a much more grounded approach to game-play that isn't seen in most games. Players must actually think about the objective and every way to approach it in order to win.

Each match pits a group of five players against another team of five to either defend or attack a position. Unlike most online shooters, you choose an operator to play that comes with their own special ability that either aids the team or hinders the enemy.

Some operators have a very real (but kinda lame) ability like having a regular old thermal scope or just having a sledgehammer. Other abilities were kind of made solely for the game and would be kinda pointless in actual combat, like a loud flying drone. But looking at their load-out, some operators would do a hell of a job in an actual scenario.
