Level III body armor is designed to provide improved defense against a range of ballistic threats. Advanced materials that both absorb and disperse impact energy are used to make these body armor. Compared to body armours with lower ratings, this form of armor provides a higher level of defense

Level III body armor provides protection against certain types of ammunition, such as the 7.62 x 51 mm NATO Ball Round and the 7.62 x 39 AK47 Mild Steel Core rounds. These armors are appropriate for military and law enforcement professionals who encounter such threats in the field.

At Hard Shell, Level III body armor plates are available in two categories: In Conjunction With (ICW) armor plates in 1.4 kg and 2.9 kg, and Stand Alone (SA) plates in 1.60 kg and 3.2 kg. Users can customize these weight options to meet their unique operational needs and preferences.

While using In Conjunction With (ICW) Level III body armor, it is necessary to put extra soft armor beneath the plate for maximum protection. As opposed to this, Stand Alone (SA) Level III body armor offers self-sufficiency by autonomously providing the necessary ballistic resistance without the need for additional soft armor.

Body armor classified as Level III and Level IV have different functions. Level IV's resistance to higher-caliber ammunition allows it to provide stronger protection against ballistic threats. Nonetheless, Level III offers sufficient protection from standard rifle bullets. The preference about the applicability of each type of armor is based on the particular threat profile and operational requirements.

The level of threat assessment and operational requirements of the user determines the suitability of Level III body armor. It is appropriate for a variety of ballistic threats. To ascertain if Level III body armor provides the appropriate degree of protection, it is imperative to assess particular ballistic threats and mission requirements.
