Which statement correctly describes a flak jacket's protective capability?

• A. It protects against bullets
• B. It protects against fragments but not bullets
• C. It protects against heat
• D. It provides no protection

Answer: (B)

Flak jackets are designed to shield the wearer from fragmentation—shrapnel and debris that result from blasts. They work by catching and slowing down flying fragments so they don’t penetrate the body, distributing the impact energy. That makes the statement that they protect against fragments but not bullets the best description: while some fragments or very small projectiles might be slowed, these jackets are not designed or rated to stop most bullets, especially rifle rounds. Heat protection isn’t their function, and saying they provide no protection would be incorrect since they do offer fragment protection.
