What tactics did the japanese use to defend okinawa? check all that apply

The Battle of Iwo Jima was fought between the Japanese army and the United States Marine Corps (USMC). The battle, known to the USMC as "Operation Detachment", started on February 19, 1945 and lasted until March 26, 1945 when the last Japanese soldiers were captured or killed.

The Battle of Okinawa was the last major battle of World War II, and one of the bloodiest. On April 1, 1945—Easter Sunday—the Navy’s Fifth Fleet and more than 180,000 U.S. Army and U.S. Marine Corps troops descended on the Pacific island of Okinawa for a final push towards Japan. The invasion was part of Operation Iceberg, a complex plan to invade and occupy the Ryukyu Islands, including Okinawa.

Okinawa Island  

By the time American troops landed on Okinawa, the war on the European front was nearing its end. Allied and Soviet troops had liberated much of Nazi-occupied Europe and were just weeks away from forcing Germany’s unconditional surrender.

On the Pacific front, however, American forces were still painstakingly conquering Japan’s Home Islands, one after another. After obliterating Japanese troops in the brutal Battle of Iwo Jima, they set their sights on the isolated island of Okinawa, their last stop before reaching Japan.

Okinawa’s 466 square miles of dense foliage, hills and trees made it the perfect location for the Japanese High Command’s last stand to protect their motherland. They knew if Okinawa fell, so would Japan. The Americans knew securing Okinawa’s airbases was critical to launching a successful Japanese invasion.

Landing on the Beachheads  

As dawn arrived on April 1, morale was low among American troops as the Fifth Fleet launched the largest bombardment ever to support a troop landing to soften Japanese defenses.

Soldiers and Army brass alike expected the beach landings to be a massacre worse than D-Day. But the Fifth Fleet’s offensive onslaught was almost pointless and landing troops could have literally swum to shore—surprisingly, the expected mass of awaiting Japanese troops wasn’t there.

On D-Day, American troops fought hard for every inch of beachhead—but troops landing on Okinawa’s beaches surged inland with little resistance. Wave after wave of troops, tanks, ammunition and supplies went ashore almost effortlessly within hours. The troops quickly secured both Kadena and Yontan airfields.

The Enemy Waits  

Japan’s 32nd Army, some 130,000 men strong and commanded by Lt. Gen. Mitsuru Ushijima, defended Okinawa. The military force also included an unknown number of conscripted civilians and unarmed Home Guards known as Boeitai.

As they moved inland, American troops wondered when and where they’d finally encounter enemy resistance. What they didn’t know was the Japanese Imperial Army had them just where they wanted them.
