• India context (2024–2025): Several reports covered nationwide civil defense mock drills with air-raid sirens, blackout exercises, and civilian training across hundreds of districts in response to security tensions and specific incidents. These drills were intended to raise awareness and test emergency response coordination.[1][3]
• Singapore context: Public Warning System sirens are used in both routine and special Exercise SG Ready events, with islandwide tests sometimes rescheduled to align with national defence-day activities.[4][8]
• Global practice: Some countries schedule annual or semiannual siren tests as part of civil defense readiness, while others embed siren usage within civil emergency drills, public education campaigns, and infrastructure security reviews.[9][10]
