Why were flares dropped with parachutes in World War II?

Flares were dropped with parachutes in World War II to illuminate areas for nighttime operations, aiding in target identification and navigation for ground troops and aircraft. The parachute allowed the flares to descend slowly, providing a sustained light source rather than a quick flash, which helped minimize the risk of enemy detection and maximized visibility over longer periods. This tactic was crucial for coordinating attacks, conducting reconnaissance, and enhancing overall battlefield awareness during nighttime missions.
