Napalm was originally developed in 1942 in a secret laboratory at Harvard University, by a team led by chemist Louis Fieser under the United States
High-explosive incendiary less practical for anti-tank work, and more useful for destroying “soft” targets such as air bases, trenches, or bunkers, in which they can create fires of over 1000 degrees Celsius. Incendiary shells are no longer in use by many countries, due to bans on the use of phosphorus weapons. Armor-piercing shot and shell penetrate the target using kinetic energy before the incendiary charge ignites, smothering the crew in flames, detonating ammunition, and destroying the target. High-explosive incendiary In warfare, High-explosive incendiary (HEI) is a type of ammunition specially designed to impart energy and therefore damage to its target in one
