FORT IRWIN, California -- Anyone who's been here has seen it: the field of brightly painted boulders surrounding a small mountain of rocks that symbolizes unit pride at the Army's National Training Center.

For nearly four decades, combat units have painted their insignias on boulders near the road into this post. It's known as Painted Rocks.

"It's a big tradition," said NTC Command Sgt. Major Matthew Lowe. "The higher you go, the older they are. If you are out there and you look toward the top, you can see the old acorn for the 24th Infantry Division with a big three on there; that unit has probably been deactivated since 1994."

Lowe was close; the 24th was inactivated in 1996, but the unit's painting is still old.

The tradition dates back to the mid-1960s when Col. Robert Osbourne, the post commander at the time, kept a concrete burro to represent the many burros that gather in San Bernardino County, where the post is located, Lowe said.

NTC did not exist yet, but units would come here to train before going to Vietnam, he said.

The 36th Engineer Battalion was here training and decided to paint Osbourne's burro.

"Of course, Colonel Osborne saw that and was not pleased, and they repainted it. And then, every couple weeks, this kept happening, where the burro kept getting painted," Lowe said.

"One day, they went out there and burro was gone and, a couple of weeks later, Colonel Osborne got a letter from Private Burro in Vietnam, with a picture of him serving his country in Vietnam," he continued.

Osbourne realized that this tradition was going to continue, so he designated an area where units could paint their insignia, Lowe explained. "And out there, Painted Rocks was born."

That was in 1967, "but it really didn't catch on until we became the National Training Center," he said. "The idea for NTC was born in the late 1970s, and we did our first rotation in 1981."

The 3rd Infantry Division's 2nd Brigade Combat Team is currently at NTC, and "there will probably be five rocks added after this rotation because battalions like to do it; separate companies like to do it," Lowe said. "The Japan Ground Self Defense Force was here in February with a company team, and they painted a rock and put it out there."

NTC officials don't know exactly how many rocks have been painted.

"Since 1981, you figure every rotation -- nine or 10 a year for the last 38 years -- units have been dropping rocks there," Lowe said. "And you don't paint over someone else's rock. That's a big no-no."

Despite what you may have heard, the Army has not declared war on mustaches.

The Army W.T.F! Moments Facebook page on Monday posted a memo written by a 3rd Infantry Division company commander telling his soldiers that only the fittest among them will be allowed to sprout facial hair under their warrior nostrils.

"During my tenure at Battle Company, I have noticed a direct correlation between mustaches and a lack of physical fitness," the memo says. "In an effort to increase the physical fitness of Battle Company, mustaches will not be authorized for any soldier earning less than a 300 on the APFT [Army Physical Fitness Test]."

The Defense Visual Information Distribution Service (DVIDS) is the largest official database of U.S. military media available for public consumption. It is also an occasional source of unexpected laughs, like this gem from a live fire exercise that a public affairs officer simply tagged 'Fire mortar boom.' In the world of droll data entry and too many acronyms, sometimes little jokes are their own little form of rebellion, right?

But some DVIDS uploads, however, come with captions and titles that cut right to the core, perfectly capturing the essence of life in the U.S. military in a way that makes you sigh, facepalm, and utter a mournful, 'too real.'
