Under MOPP 4, which items are worn?

• A. All worn: overgarment, mask, gloves, overboots, field gear, body armor
• B. Only the mask and gloves
• C. Helmet and shield
• D. Boots and trousers

Answer: (A)

MOPP 4 is about wearing the full NBC protective ensemble to maximize protection against chemical and biological threats. This means you don the protective overgarment to cover the body, the protective mask for respiration, and seal with gloves and overboots to guard the hands and feet. In many field situations you also keep on your standard field gear and body armor, since they support mission capability and don’t interfere with the protective suit when properly worn. The other options fail because they omit essential NBC protection (like the mask or overgarment) or refer to items not sufficient on their own to meet MOPP 4’s level of protection.
