In 1942, on Guadalcanal Island, the 1st Marine Division occupied the Japanese airfield on the island, thus launching a strategic counteroffensive against Japan in the Pacific War. Three U.S. Marines, Leckie, Sledge and Basron, went through the deadliest Pacific War in World War II. In the Pacific, the Japanese army was arrogant and launched a fierce offensive against the US military, during which there was no shortage of suicide attacks. From the fierce Battle of Guadalcanal, the landing of Cape Gloucester, and the Battle of the Tropical Jungle, the Battle of Peleliu, to the Battle of Iwo Jima and Okinawa. Leckie (James Becky Dale James Badge Dale), Sledge (Joseph Metzelo Joseph Mazzello) and Basron (Jon Cedar Jon Seda) witness the Japanese struggle until the final rout, and see their comrades-in-arms constantly dying in this fierce battle. HBO, the most expensive American TV series in World War II, cost $223 million, which is the second time Spielberg and Tom Hanks have teamed up after the Brothers.
