News You Can Use
- Throughout history there have been countless variations of body armor. From as early as the Roman Empire, armies have used various forms of protective clothing to prevent injury on the battlefield.
- While there are many variations, they all can be broken down into two types: soft body armor or hard body armor. Soft body armor is traditionally used when the threat is from standard bullets or knives, while hard armor is for the high risk scenarios seen by tactical units or soldiers.
- Each type of armor traditionally is made up of two sections, soft inner panels and the outer carrier. The outer section can simply been seen as a casing to hold the special panels that are inside, because without the panels, there is no protection.
- The soft inner panels are traditionally made from a very lightweight and durable polymer such as Kevlar. This polymer's main purpose in armor is to absorb as much of the kinetic energy and momentum of whatever strikes it. Through patented forms of weaving the polymer to the number of actual layers used, Kevlar based body armor is able to stop some ballistics that most other materials cannot.
