How often do ICBM operators swap out?

• A. Every Week
• B. Every Month
• C. Every Quarter
• D. Every Year

Answer: (B)

Monthly rotations are used to keep ICBM operators fresh while preserving continuity of watch. The duty is highly cognitive and time‑critical, so changing the on‑alert team each month allows thorough handoffs, gives the incoming crew time to review procedures and maintain proficiency, and provides a reasonable rest period to reduce fatigue and complacency. This cadence balances the need for ongoing readiness with the practicalities of training and certification schedules. Weekly changes would be too disruptive, while yearly changes risk skill drift and lost familiarity with procedures; monthly is the standard balance that supports sustained effectiveness.
