The Green Signal Lamps on Omaha

Why did some assault leaders on Omaha Beach carry colored signal lamps into the surf?

Because radios were expected to fail in the surf and smoke. Officers used colored lamps and hand signals to rally scattered men and identify temporary control points when companies landed badly mixed together.

Why it matters: This detail shows how invasion planners expected chaos and built in low-tech backups for command and control.
