A strange electromagnetic storm threw the modern special operations company "Knives", which was conducting a live-fire exercise, back to the Pacific battlefield in 1942, including men and equipment. They were forced to land on an isolated island controlled by the Japanese army, and suddenly clashed with their sworn enemy in history.
Taking advantage of equipment generation differences, the "sharp blade" first showed its edge, and night vision devices became a nightmare for the Japanese. Precise sniping killed enemy chiefs thousands of meters away. They were forced to form an alliance with the dubious US military, and were thrown into the flesh-and-blood furnaces of Guadalcanal and Iwo Jima under the codename "Dragon Force".
However, the missile malfunctioned, communications were interrupted, and ammunition was in short supply. They must use empty spear thrusts, blunt tactical knives, and the iron will from the future to fight their way through the desperate battlefield. They are the lost people fighting for survival, and they are also the unknown heroic souls who poured their blood into victory. When the final victory came, they stood in the glory of history, but faced the eternal confusion of being unable to go home. This is a group of time-travel warriors who used the most advanced tactics and the most primitive courage to write an iron-blooded legend on the Pacific battlefield.
Basically OK.
