What does L-Hour refer to?

What does L-Hour refer to?

• A. Time at which first helicopter touches down in landing zone
• B. Time first assault elements touch down on beach
• C. Time D-Day commences
• D. Time line of departure

Answer: (A)

L-Hour is the moment the air assault begins—the first helicopter lands in the landing zone to insert the assault troops. The letter L points to lift/landing, signaling the start of the aerial insertion phase. This time is chosen to sync the initial helicopter arrivals with follow-on troops, security, and supporting fires so the objective can be seized in a coordinated push. It’s distinct from the moment the main beach assault begins (that event is H-hour) and from departure or broader operation start times.
