Armour
Armour, also called body armour, is protective clothing with the ability to deflect or absorb the impact of projectiles or other weapons that may be used against its wearer. Modern technology has brought about the development of lighter protective materials that are fashioned into various apparel suited to the hazards of modern warfare. With the rise of terrorism and the use of powerful personal weapons by criminals, armor is now frequently worn by police, private nonmilitary security forces, and noncombatants who might be targets of attack [Mansoor, P., par. 1].
Armed forces worldwide utilize some form of body armour as part of their protective system. This is particularly essential in recent times because of the increased sophistication of weapons employed during modern warfare and the advent of unconventional combat methods (such as the increased use of improvised explosive devices). However, there is some evidence to show that military body armour impairs physical performance. The observed performance decrements may also be exacerbated when soldiers carry their full combat load and protective body armour. Still, the precise relationship between the degree of performance decrement with increasing equipment load is yet to be identified [Larsen, B., Netto, K. and Aisbett, B., p 1271].
