The Sig Sauer P226: The Navy SEALs' Favorite Gun

For three decades, the U.S. Navy’s Sea Air Land (SEAL) special-forces teams relied on a pistol apart from the rest of the American military. While the Army, the Marine Corps and even the rest of the Navy toted the Beretta M9 pistol, Navy SEALs carried an entirely different handgun altogether: the Sig Sauer P226.

The M2 Carbine: America's First Assault Rifle?

Germany is generally credited with developing the first assault rifle with the MP-43, which entered service with select units towards the end of 1943. Later renamed the Sturmgewehr 44—literally “assault rifle 44”—this used an intermediate-strength kurz cartridge that balanced the long-range accuracy of heavy, slow-firing bolt-action rifles then prevalent with the automatic-fire capability of submachine guns, which were deadlier at close quarters and capable of laying heavy suppressing fire for infantry assaults.

From Russia with Bombs: How China's Big 'Guns' Could Wage War

One of the hallmarks of Soviet (now Russian) artillery doctrine was a focus on rapid, devastating fire. The Soviets noticed that the effectiveness of a barrage quickly wore off after time as the targets took cover, so significant effort was spent maximizing the initial volume of fire. To facilitate this, the doctrine called for heavy use of rocket artillery such as the BM-21 Grad, which has an extremely rapid rate of fire by design. Additionally, self-propelled guns such as the 2S19 Msta-S were designed with autoloaders that could load rounds faster than humans.
