Luke T. asks: How many times can you shoot a bulletproof vest before it stops working?
To begin with, it should probably be noted that the name "bulletproof vest" is a misnomer with "bullet resistant vest" being more apt. Or to quote John Geshay, marketing director for body armor company Safariland, "…nothing can be bulletproof, not even a manhole cover. In an extremely small percentage of cases, a round can even go through a vest that it is rated to stop. The round itself could have an extra serration on it or something."
Furthermore, body armor designed to protect the wearer from high caliber guns can still be penetrated or compromised by smaller caliber bullets. For example, armor designed to stop a round from a .44 Magnum (the kind of round Dirty Harry claims can blow a man's head clean off) could theoretically be pierced by a 9mm round if the latter is fired with a high enough muzzle velocity, with distance to the target also playing a role. Or as Police Magazine notes, "There's a tendency among gun enthusiasts to dismiss the lethal potential of certain calibers of handguns. Don't believe it. A small round traveling at high speed can punch through body armor."
For some guys, the structure and routine of hitting the gym is exactly what they need to keep their fitness on track. For others, it's a slog. The space is dark, the treadmills relentless, and the music mind-numbing. You'd rather be outside, shooting hoops with your boys. Which, actually, you should be, since a pick-up game of basketball burns more calories and builds more muscles than any 30-minute session on the elliptical ever could.
If sports excite you more than spin class, and the idea of scoring points matters more than how much you can bench press, consider these activities that emphasize team spirit and gamesmanship while getting you, incidentally, super fit.
Although it will be years before the first humans set foot on Mars, NASA is giving the public an opportunity to send their names — stenciled on chips — to the Red Planet with NASA's Mars 2020 rover, which represents the initial leg of humanity's first round trip to another planet. The rover is scheduled to launch as early as July 2020, with the spacecraft expected to touch down on Mars in February 2021.
The rover, a robotic scientist weighing more than 2,300 pounds (1,000 kilograms), will search for signs of past microbial life, characterize the planet's climate and geology, collect samples for future return to Earth, and pave the way for human exploration of the Red Planet.
There was a lot of new technology brought to the battlefield during World War I. Two of those were used in tandem – and somehow managed to perfectly compliment each other. It was the fighter plane and the machine gun, mounted perfectly for the pilot's use, without shooting up the propeller that kept the bird aloft.
As the U.S. maps out plans to protect American military bases susceptible to climate change, its partner nations are growing increasingly concerned that global warming may lead to weapons and technology proliferation as now-frozen waterways open.
Norwegian officials worry that melting Arctic ice will lead players such as Russia, China, and the U.S. to increase use of undersea and aerial unmanned weapons as well as intelligence gathering platforms in the newly opened areas.
The drones could be programmed to "follow strategic assets," including Norwegian or ally submarines, a top Norwegian Ministry of Defense official said in early May 2019.
He added that the presence of such drones may increase the potential for collisions.
"I don't think all these unmanned things work perfectly at all times," he said.
Being a POW was not a great way to spend your enlistment in the Civil War, no matter which side you fought on. Depending on which POW camp you ended up locked into, your chances of survival were only slightly better. And if you did die, you probably died of some terrible disease.
So it makes a little sense why some Confederate troops had no problem turning around and joining the U.S. Army. They were called "Galvanized Yankees."
Master Sergeant George Hand US Army (ret) was a member of the 1st Special Forces Operational Detachment-Delta, The Delta Force. He is a now a master photographer, cartoonist and storyteller.
Master Sergeant Bill — and that was his real last name — had a trick back, so he claimed. It seemed to flare up just as we were on the cusp of an unpleasant mission. My gosh, it didn't seem to trouble him much at all during "good deal" trips, no Sir. Whether or not it was a valid ailment, that we shall never know, but the timing of the affliction sure seemed suspect over the years.
Well sure, I understood as well as the next man, that with all of the non-stop training we did to satisfy our charter to deploy in just a few hours, to deploy to the four corners of the planet and be ready to sustain combat for several days... a brother just needed a break now and then to harness and hold a semblance of sanity — "to each his own," I often rationalized.
Turkey's defense minister said Ankara was preparing for potential U.S. sanctions over its purchase of Russian S-400 missile defense systems, but also spoke of what he called a growing "rapprochement" with Washington over the issue.
The United States has demanded that Ankara call off the deal to purchase the Russian system, and NATO allies have also expressed concerns about the potential threat to U.S.-made F-35 fighter jets.
Grab a cookie and get in the chair.
Imagine going into the Emergency Room, bleeding from a car accident. The EMTs tell you it doesn't have to be a serious injury as long as they can handle the blood loss. Imagine then being told they can't actually handle the blood loss – even at the hospital.
That's the reality the American Red Cross is facing today. It has only two days worth of Type-O blood left for the entire United States. Just six units for every 100,000 people.
