A tank with sufficient armour could resist the largest anti-tank guns then in use. RHA was commonly used during this period (combined with other plate alloys and cast steel armour), and the power of anti-tank guns was measured by the thickness of RHA they could penetrate. This standard test has remained in use despite the modern usage of many ...
An illustration of why sloped armour offers no weight benefit when protecting a certain frontal area. Comparing a vertical slab of armour (left) and a section of 45° sloped armour (right), the horizontal distance through the armour (black arrows) is the same, but the normal thickness of the sloped armour (green arrow) is less.
US Marine Corps M1A1 on a live fire exercise in Iraq, 2003. It is a modern Main Battle Tank that extensively uses Chobham armour. In the United Kingdom application of Chobham armour was delayed by the failure of several advanced tank projects: first that of a joint German-British main battle tank; then the purely British MBT-80 programme.
The advanced Kontakt-5 explosive reactive armour on this T-90S is arranged in pairs of plates, giving the turret its prominent triangular profile.. An element of explosive reactive armour (ERA) is made of either a sheet or slab of high explosive sandwiched between two metal plates, or multiple "banana shaped" rods filled with high explosive which are referred to as shaped charges.
The U.S. Army's M1 Abrams MBT with TUSK (Tank Urban Survival Kit) upgrade uses composite, reactive and slat armour. Military vehicles are commonly armoured (or armored; see spelling differences) to withstand the impact of shrapnel, bullets, shells, rockets, and missiles, protecting the personnel inside from enemy fire.

Frag Kit 6 is a vehicular armor upgrade kit developed by the U.S. Army Research Laboratory to defeat explosively formed projectiles (EFP), a type of armor penetrator often utilized in improvised explosive devices (IED). It is designed to be added on armored vehicles such as the MRAP and unarmored Humvee. [1]
Tank spaced armour has been fielded since the First World War, when it was fitted to the French Schneider CA1 and Saint-Chamond tanks. The late variants of Panzer III had frontal spaced armour: a 20 mm thick face-hardened steel layer in front of the 50 mm thick main armour. Impacted projectiles were physically damaged by the 20mm plate, so the ...
