The no-lone zone and two-person rule together help maintain proper control over nuclear weapons and reduce risk of unauthorized actions.

• A. True
• B. False
• C. Only during exercises
• D. Not relevant

Answer: (A)

These controls create a system of checks and balances for handling nuclear weapons. A no-lone zone prevents anyone from being alone with a weapon, ensuring there is always at least one other responsible individual nearby to observe and intervene if needed. The two-person rule requires two authorized operators to perform actions, providing independent verification and shared responsibility. Together, they reduce the risk of unauthorized actions by blocking single-person access and adding supervisory review, accountability, and cross-checks throughout handling, movement, and use. They are applied during real operations and training alike, so they’re not limited to exercises.
