The Sturmpanzer was a development of the Panzer IV tank designed to provide a vehicle offering direct infantry fire support, especially in urban areas. It used a Panzer IV chassis with the upper hull and turret replaced by a new casemate-style armored superstructure housing a new gun, the 15-centimetre (5.9 in) Sturmhaubitze (StuH) 43 L/12 developed by Skoda.

The M5 Stuart light tank made its debut in the invasion of Casablanca in French North Africa. By 1943, and at the time of the invasion of Sicily, the upgraded M5A1 was becoming the standard light tank of the American armored divisions. Because of limited firepower, the M5A1 eventually took on reconnaissance and escort duties in Italy and, after the invasion of Normandy, throughout Europe.

The Lockheed SR-71 was an advanced, long-range, Mach 3 strategic reconnaissance aircraft developed from the Lockheed A-12 and YF-12A aircraft by the Lockheed Skunk Works. The SR-71 was unofficially named the Blackbird, and called the Habu by its crews.

The first generation T-34 medium tank made its debut in combat during the summer of 1941, when the Wehrmacht launched its invasion of the Soviet Union. The T-34 easily outclassed the German PzKpfw III and IV models, thanks to its hard-hitting 76.2mm main gun, thick frontal armor, wide tracks, and overall superior mobility.

The M10 were, numerically, the most important US tank destroyer of World War II. In its combat debut in the North African campaign, the M10 was successful as its M7 3-inch gun could penetrate most German tanks then in service at long range.
