The Red Line Daisan Ji Oshu Taisen Ka / Original Title: the RED LINE (Take Shobo Bunko)

[Machine Translation] The U.S. forces, overwhelmed by the gap in strength without being able to mount an organized resistance, attempted to restore the command and communication system using a communications facility that had barely repelled the enemy as a foothold, and succeeded in partially restoring the system. Although there was a glimmer of hope, the overwhelming gap in strength could not be filled. The U.S. was still in a defensive position, and its inferiority remained unchanged. Berlin falls to the Soviet forces, which continue their onslaught. Arrested neo-Nazi leader Fromisch was immediately executed, and the news was broadcast to the world. The Soviets were no longer in a position to doubt their victory, but the American forces continued to mount a stubborn resistance. Secretary General Cheninko finally ordered the use of nerve gas and small nuclear weapons. While the Soviets are convinced that there is no way out for the Americans, who have lost the largest air base in Europe in an instant, the U.S. European Command is now in the midst of a desperate maneuver to save their lives. However, in order to complete the operation, it was necessary to "buy time" assuming all possible sacrifices. With the war situation worsening by the minute, the President of the United States is faced with a final choice... The presidential decree is issued: the nuclear threat is unleashed.
