The Sukhoi PAK FA (Russian: Perspektivny Aviatsionny Kompleks Frontovoy Aviatsii, literally "Prospective Airborne Complex of Frontline Aviation") is a twin-engine jet fighter being developed by Sukhoi for the Russian Air Force. The Sukhoi T-50 is the prototype for PAK FA. The PAK FA is one of only a handful of stealth jet programs worldwide.

The Sukhoi Su-35 (NATO reporting name: Flanker-E) Also known as Super Flanker, is a designation for two separate, heavily upgraded derivatives of the Su-27 'Flanker'.

The "Churchill" began life as a 1939 requirement that envisaged a return to trench-warfare, and was therefore slow and heavily armored like the Russian KV-1 series. That said, the final Churchill prototype was much lighter than had first been thought acceptable, although it still resembled a World War I tank in appearance.

By all accounts, the M4 Sherman medium tank was regarded as the workhorse of the US Army during World War II. In fact, virtually all of the Allied armies employed the Sherman in their armed forces, including the British, who developed an upgunned variant called the "Firefly".

The M24 Chaffee - arguably the best light tank of World War II - was a fast, lightly armored vehicle with the ability to deliver relatively large caliber direct fire thanks to its excellent 75 mm M6 gun. More than 4,000 vehicles were produced by Cadillac and Massey-Harris from 1943-45.
