Which statement correctly describes a flak jacket's material and the protection it offers?

• A. Kevlar; protects against bullets
• B. Ballistic nylon; protects against fragments but not bullets
• C. Cotton; protects against nothing
• D. Steel; provides full protection against bullets

Answer: (B)

Flak jackets are designed to absorb and slow fragmenting debris from blasts, not to be fully bulletproof. They use strong protective fabrics, such as Kevlar or ballistic nylon, to reduce injury from shrapnel. The key idea is that this kind of armor provides protection mainly against fragments, while bullets—especially higher-velocity rifle rounds—are not reliably stopped by such gear. Among the options, describing the jacket as made of ballistic nylon and providing protection against fragments but not bullets matches how these vests are typically described and used. The other choices either imply bulletproof capability that soft armor cannot guarantee, or cite materials not representative of standard flak jackets.
