It's almost 10pm on the night of Monday, December 8th, 1941. The White House, the residence of President Franklin Delano Roosevelt, has finally calmed down since the Pearl Harbor attack brought unceasing chaos to the US Government Sunday afternoon and all today, until about half a hour ago. Finally, peace and quiet, despite the fact the United States of America had declared war today on the Empire of Japan. President Roosevelt was trying to relax in his office with camel cigarettes and his own version of a martini cocktail. As ten o'clock chimed away on the White House Grandfather clocks, there was a knock on the door and entered a Colonel War Cloud. Harry Hopkins, the President's Chief Advisor, had set up a late night meeting between the President and the Colonel to discuss a special project President Roosevelt wanted to activate immediately. That project is The Intruders, a special international commando team operating under the guidance of a newly formed international organization, the President would soon be calling the United Nations. The Intruders mission, based on the three D's, is to Detect enemy secret weapons facility locations, Determine enemy secret weapons potentiality, and Destroy enemy secret weapons programs before such wonder weapons are released onto the battlefield or used on targeted cities. General War Cloud would select top Commandos from around the World and train his Intruders, Team 52, in the Arizona desert and then prepare for their first mission against the Japanese called Operation Rookie.

In the freezing cold of the Egyptian desert, the cloudless night sky glistens with what seems to be a thousand stars twinkling above the Earth and the windless evening was so tranquil and peaceful, you would never of known this was part of a combat zone. A combat zone that was expanding further across North Africa as Rommel's Afrika Corps pushed the British out of Libya into the realm of Egypt, where the Western Desert Campaign was developing into a climax between the Axis Powers and the Allied Powers of who would triumph in the region once and for all. The British were in the process of developing defensive positions near El Alamein to outfox the Desert Fox or deal with the consequences of losing Egypt, the Suez Canal, and even the oil rich Arabian Peninsula. A lone British soldier stood sentry in the dark shivering from the coldness of the Sahara Desert, stands watch over a small camp seven kilometers west of El Alamein, where three American made British M3 Grant battle tanks made camp for the night. The tank crews were sleeping on the ground in makeshift tents, while a few tankers slept in their tanks, instead of dealing with the sandy desert ground. Suddenly, the desert still of the night was disturbed as the ground began to rumble and shake. The British sentry was trying to balance himself, but was knocked off his feet as the desert ground opened up with a storm of sand drenching the air. As the British sentry tried to clear the grainy sand out of his eyes, he heard a loud mechanical twirling sound and then his vision cleared with the image of a humongous cylinder shaped machine mounted with a high velocity still spinning drill. The British sentry was trying to understand what he saw before him. He did not fully comprehend what he saw, but the machine was a tank-like boring machine, capable of drilling deep down into sand, dirt, and stone called a Subterrene.
