In James Cameron's latest sci-fi epic Avatar, a paraplegic ex-marine travels to a remote planet inhabited by an exotic humanoid race called the Na'vi. Using their advanced technology, he is made whole as an Avatar, an alien body that is remotely controlled by his human mind. When a conflict between the Na'vi and the humans breaks out, he is forced to take a side.

In Avatar the movie, the RDA (Resources Development Administration) is the largest single non-governmental organization in the human universe. It has monopoly rights to all products shipped, derived, or developed from Pandora and any other off-Earth location. All humans on Pandora, are employed by RDA.

The RDA Military originally were on Pandora to provide protection for the scientists, however, their priorities change after the discovery of Unobtainium (a precious resource which the RDA Military want to send back for use on Earth). Unfortunately Pandora's greatest source of Unobtainium is under Na'vi sacred ground, a place the scientists want to respect but the RDA Military is willing to exploit. Colonel Miles Quaritch (Stephen Lang) is Head of RDA Military on Pandora. He (and all his staff) wear the RDA Military Dog Tag at all times.

Not only are these exact replicas of the Dog Tags from the movie, you can also add your personal details and put them around your neck as if you were in the movie yourself!
