Oshkosh JLTV

When battle requires a heavily armored vehicle that's faster than a tank, it may be time for the Halo-inspired Oshkosh Defense JLTV. The company was originally going to arm them with .50 caliber (12.7 mm) heavy machine guns, 7.62 mm light machine guns, grenade launchers, ande anti-tank missiles, but now they've added a 30mm chaingun, the same ones found on Apache attack helicopters. This extra range and firepower enables soldiers to employ the vehicle much more aggressively, such as a forward scout moving out fast and ahead of the main force.

Origami Bulletproof Shield

This may look like art at first, but it's a functional bulletproof shield. Designed by engineers and students at BYU, this folding Kevlar shield, modeled after origami practices, can stop .44 magnum bullets, thanks to 12 layers of Kevlar with aluminum panels in the middle to give it strength. "Current products out there are about 90 pounds. That's pretty heavy for one person to carry. Our goal was to go for 50 pounds and protect two to three people," said Terri Bateman, adjunct professor of mechanical engineering at BYU.

Tracer Pulse Gun

Overwatch fans rejoice! Inventor Patrick Priebe of Laser Gadgets has created a fully-functional Tracer Pulse Gun, and visually, it looks to match its video game counterpart, while the side "has spinners". Users can switch in / out of pulse firing, and you can set lots of things on fire when you're bored. Unlike the game, these do not have a large cone of fire nor a heavy damage dropoff, which make them ineffective beyond short range engagements.

Nazi Belt Buckle Pistol

The SS Officer belt buckle pistol was an experimental German World War II firearm consisting of four 7.65 mm or .22 long rifle barrels and lockwork concealed within a Nazi Party belt buckle. The barrels were 2" long and the wearer needed to get very close to their victim. A lever was pressed which allowed the spring-loaded buckle to pivot downwards, exposing the barrel. Noted firearms authority S.P. Fjestad claims that they were designed by Louis Marquis while he was in a prisoner of war camp during World War I and that fewer than ten of these guns have been discovered.

Implant-Activated Smart Gun

Biohacker Amal Graafstra has created a prototype for the world's first implant-activated "smart gun," which requires an embedded chip be implanted under the skin between the thumb and forefinger. When a user picks up their weapon, the gun would unlock only for the person with the implant. "I think the smart gun concept is important, because eventually we'd be able to control who's able to operate the weapon once it leaves the store," said Graafstra.
