Armor plates usually used for body armor, but they not restricted to bulletproof vests and plate carriers. In fact, they have a broad range of application. These level IV flat bulletproof plates without curve are often used in objects to provide them with ballistic protection.
These armor plates can be used in vehicles, this can be done by adding these armor plates to existing vehicles with minimum changes.
In some cases when ballistic protection needed in a bag or a backpack, you can use these plates by putting them in the bag or a backpack (for this we usually use plates with custom size).
These plates also can be used in ballistic shields, in a row as they not curved and can be used as a chain for bigger protection area.
