Diamond Dogs / 1984

“Diamond Dogs was a private military company led by Venom Snake around the 1980s. It was created as a result of the devastation of the Militaires Sans Frontières as well as the attack on Mother Base. At some point during the 1980s, Diamond Dogs managed to situate themselves on an offshore plant modeled after their former base given to them by the government of the Seychelles after they halted an attempted coup by South African mercenaries. The name stems from the group’s profession as “dogs of war,” who were willing to carry out unsavory jobs for clients, while at the same time maintaining pride in their work. Owing to their name, they also carried diamonds into battle, some converted from the cremated ashes of their fallen comrades, and collected raw diamonds for the funding of their Mother Base. Besides engaging in combat and various mercenary jobs, the Diamond Dogs also retrieved various animals for an environmental NGO.

The Diamond Dogs’ practice of carrying diamonds into battle began after an outbreak of parasites occurred, which resulted in Venom Snake being forced to kill a large number of his comrades. After the incident, the cremated bodies’ ashes were turned into diamonds.

At some point, the Diamond Dogs had decided to follow the world’s example of disarming their own nukes. Their first attempt at disarming a nuke had the nuclear material rupture, also irradiating several men in 100 rads and had to be hospitalized as a result, although they had nonetheless contained the leak and presumably put it in cold storage. Eventually, they needed to grow stronger to ensure nukes were eliminated, requiring development of several armored vehicles, with Ocelot noting the irony that they had to expand the war effort to eliminate nukes.

At some point before 1995, Diamond Dogs was dissolved and absorbed into Outer Heaven – Venom Snake’s independent nation.” http://metalgear.wikia.com/wiki/Diamond_Dogs
