Battlefield Heroes Gets Bad Company

The USS Eldridge (DE-173), a Cannon-class destroyer escort, was a ship of the United States Navy named for Lieutenant Commander John Eldridge, Jr., a hero of the invasion of the Solomon Islands.

Philadelphia Experiment
The Philadelphia Experiment was an alleged naval military experiment at the Philadelphia Naval Shipyard in Philadelphia, Pennsylvania, sometime around 28 October 1943, in which the Eldridge was to be rendered invisible (i.e. by a cloaking device) to human observers for a brief period. It is also referred to as Project Rainbow. In the Battlefield Heros Gets Bad Company Trailer, the background behind Arkady Kirilenko and George Haggard ending up in the Heros Universe is because of the experiment, in which the Scalar Weapon was used to make the USS Eldridge invisible. However, the experiment that takes place is in March 16th, 2010, not 1943.
