What level of protection does a Level 11A vest offer?

A Level 11A vest provides protection against specific types of handgun threats, including some high-velocity rounds. The classification is designed to safeguard wearers from a variety of handguns, including those that might fire standard-velocity rounds and certain lesser-known high-velocity threats.

High-velocity weapons are generally associated with their capability to penetrate certain types of armor and cause significant ballistic damage. The level classification system used for body armor delineates what types of firearms and ammunition a vest can resist effectively, with Level 11A specifically being tailored for handguns rather than rifles or submachine guns.

The other choices, while they touch on aspects of firearm protection, do not accurately represent the specific capabilities of a Level 11A vest. It is not designed to provide comprehensive protection from all firearm types or against submachine guns; instead, it has a more focused application in terms of personal defense against handguns. This makes the choice of high-velocity weapons the most accurate portrayal of the protection offered by a Level 11A vest.
