How did they distroy the bunkers D-day?

During D-Day, Allied forces targeted German bunkers on the Normandy coast using a combination of naval bombardment, aerial strikes, and specialized assault units. Battleships and destroyers fired heavy artillery at the bunkers to weaken their defenses before the landings. Additionally, aircraft dropped bombs to further damage the structures. Once the troops landed, engineers and demolition teams used explosives to breach the bunkers and neutralize their occupants.
