Ballistic resistance refers to the ability of materials or inserts to withstand the penetration of projectiles.

There are several levels of ballistic resistance, indicated by numbers or letters, which determine the types of ballistic threats the protected material or insert can resist.

Some of the most common levels include:

Level I: Protection against small-caliber handgun rounds.

Level IIA: Protection against projectiles from small handguns.

Level II: Protection against projectiles from medium-sized handguns.

Level IIIA: Protection against Magnum handgun projectiles and handguns with a caliber higher than 9mm Luger, as well as some machine gun rounds.

Level III: Protection against rifle projectiles.

Level IV: Protection against projectiles of caliber 7.62mm and higher.

It's important to note that ballistic resistance can be achieved through a combination of various materials, such as aramid fibers, polyethylene, or ceramics.

Each level provides a different level of protection and is suitable for specific situations and threats.
