Which sequence correctly lists the three Air Defense Warning Levels in order of increasing severity?

• A. White, Red, Yellow
• B. White, Yellow, Red
• C. Yellow, White, Red
• D. Red, White, Yellow

Answer: (B)

The levels escalate from normal readiness to increased readiness to full defensive action. White represents normal operations with no threat. Yellow signals increased readiness because a potential threat has been identified, so surveillance tightens and procedures are prepared. Red is maximum readiness when an attack is imminent or underway, requiring immediate defensive actions.

So the sequence that shows increasing severity is White, then Yellow, then Red. Other sequences would imply jumping from normal to high alert, or mixing levels in a way that doesn’t reflect the proper escalation of threat.
