The Army's Biggest Fear: Fighting a War Against North Korea (Underground)

Subterranean operations often deny soldiers analog or digital communications, unmanned reconnaissance and ambient light — degrading situational awareness and blocking sensors that would allow U.S. troops to otherwise peer through obscurants. Line-of-sight radio connectivity is often compromised.

U.S. Army war planners and weapons developers have been increasing efforts to fast-track networking technologies for soldiers operating underground in tunnel complexes and in dense urban environments.

Russia Has a Sneaky New Way To Sink a Navy Warship

Russia’s military spending cannot match the Kremlin’s ambitions. Western sanctions and low gas prices forced a big cut to the Russian military budget in 2017, bedeviling a host of military projects. However, Russia is looking at cheap and easy ways to equip its forces — particularly the navy — with sophisticated weapons.

Introducing the Army's Secret Weapon to Fight Russia: Super 'Cannons'

A 70-kilometer target range is, by any estimation, a substantial leap forward for artillery; when GPS guided precision 155mm artillery rounds, such as Excalibur, burst into land combat about ten years ago - its strike range was reported at roughly 30 kilometers. A self-propelled Howitzer able to hit 70-kilometers puts the weapon on par with some of the Army’s advanced land-based rockets - such as its precision-enabled Guided Multiple Launch Rocket System which also reaches 70-kilometers.

Russia's New 'Terminator' Tank Might Be Able to Kill One of America's Most Deadly Weapons

Russia is developing a third generation of its BMPT-72 Terminator combat support tank.

The vehicle, designed to support tanks and infantry, will also be able to shoot down drones, according to Russian media.

"The new vehicle will be able to operate against all types of targets: air, ground, enemy troops and material targets,"  Sergei Abramov, a director of the state-owned Rostec armament firm, told Sputnik News.

They Could End the World: 5 Most Deadly Submarines on Planet Earth

While they have thankfully never been used during a shooting war, nuclear-powered submarines carrying nuclear-tipped missiles are the most deadly weapons mankind has ever devised. In some cases—as in the case of the Ohio-class submarine during the height of the Cold War—even a single vessel could reduce as many as 288 city-sized targets into radioactive ash in less than 30 minutes. Indeed, these vessel and their payloads could end human civilization in less time than it takes to order a pizza if a third world war were to break out.
