The chilling wail of an air raid siren is more than a warning—it’s a weapon of fear, engineered to trigger panic and activate survival instincts. First used over 200 years ago, sirens became symbols of war during WWII and India’s 1965 and 1971 conflicts. Even today, their rising-and-falling cry rattles nerves, evoking memories of blackouts, bomb shelters, and resilience. This sound isn’t just history—it’s a reminder to always stay ready. #AirRaidSiren #WarAlert #SoundOfFear #IndiaWarHistory #Eme
