Similarly to SLAP rounds (saboted light armor penetrator) which get their armor-piercing ability from the propulsion of a 7.62 mm tungsten heavy alloy bullet from a 12.7 mm barrel (.50 caliber) using a sabot with much more energy than is usually possible from a 7.62 mm round, HEIAP munitions utilize a similar theory with an added explosive ...
Soviet 125 mm HEAT BK-14. The general public remained in the dark about shape charge warheads, even believing that it was a new secret explosive, until early 1945 when the US Army cooperated with the US monthly publication Popular Science on a large and detailed article on the subject titled "It makes steel flow like mud".

Aventurine is often banded and an overabundance of fuchsite may render it opaque, in which case it may be mistaken for malachite at first glance. [citation needed] The name aventurine derives from the Italian "a ventura" meaning "by chance". This is an allusion to the lucky discovery of aventurine glass or goldstone at
Advanced Modular Armor Protection (AMAP) is modular composite armour concept, developed by the German company IBD Deisenroth Engineering, since 2019 part of Rheinmetall Protection Systems. According to IBD AMAP is a 4th generation composite armour, making use of nano-ceramics and modern steel alloy technologies. [ 1 ]
Improvements in powerful automotive propulsion and suspension systems following World War II allowed modern main battle tanks to incorporate progressively thicker and heavier armor, while maintaining considerable maneuverability and speed on the battlefield. As a result, achieving deep armour penetration with gun-fired ammunition required even ...

In linear algebra, a power cone is a kind of a convex cone that is particularly important in modeling convex optimization problems. [1] [2] It is a generalization of the quadratic cone: the quadratic cone is defined using a quadratic equation (with the power 2), whereas a power cone can be defined using any power, not necessarily 2.
A pike nose (from Russian: щучий нос) is a configuration of vehicle armour in which an armoured vehicle's frontal armour consists of three angular plates put together to form a cone-like shape, similar to the nose of a pike, from which the name stems. [1] [2] Often welded, it can also be cast. [2]
