The 6 Most Powerful Armies to Ever March on the Planet

As a result, in a span of about three hundred years, Rome expanded from a regional Italian power to the master of the entire Mediterranean Sea and the lands surrounding it. The Roman Legions—divisions of the Roman Army which contained professional soldiers who served for 25 years—were well trained and well-armed with iron and were placed all over the empire in strategic locations, both holding the empire together and its enemies at bay.

The 5 Best 9mm Caliber Handguns on the Planet

The 9mm Luger, invented before the Great War, is one of the longest serving gun calibers in history. Introduced in 1901, it has served in virtually every conflict since then up until today. From World War I’s German army to the British army fighting ISIS in Syria, the Luger round has served militaries for over a century. Despite its age, the 9mm is more dangerous than ever before, due to innovations in ammunition lethality that squeeze greater performance out of the bullet.

America's F-35s, F-15s and F/A-18s Will Soon Have a New Bomb to Drop

Raytheon has completed developmental testing of the 250-pound GBU-53B Small Diameter Bomb II.

The new glide bomb, which incorporates a tri-modal seeker, will now have to complete government “confidence testing” before it enters into its operational test phase before being fielded onboard the Boeing F-15E Strike Eagle and the Boeing F/A-18E/F Super Hornet and Lockheed Martin F-35 Joint Strike Fighter. The weapon is crucial to enabling the F-35 to perform the close air support mission effectively.

China's Worst Nightmare: Imagine If Taiwan Had Nuclear Weapons

Another, far worse possibility is that Taiwan could have developed a larger, city-killing bomb. This could have been used to threaten Beijing directly, trading the destruction of one government for another, and would have been a more useful deterrent. Still, the 1,800-mile distance it would take to deliver a nuke on Beijing was at the time as insurmountable as the Taiwan Strait itself. Not even Israel had the technology to assist in developing long-range missiles or aircraft to deliver such a nuke.
