Diamond Dogs

&nbsp The Diamond Dogs are a military group. Much about them is unknown other than the fact that Big Boss is a member of it and that it possibly involves dogs.

Behind the scenes
The Diamond Dogs were first unveiled on a website of Kojima Productions that is recruiting engineers to help develop the next Metal Gear game, on classified artwork depicting Big Boss with a dog. Because of the angle of the artwork, the logo on his right side of his uniform only had "Dogs" as being readable. However, Kojima tweeted the full image of the logo, revealing the name.

The name is possibly a reference to David Bowie, of whom two references were already made in the Metal Gear Games (specifically Major Zero adopting the name Major Tom during the Virtuous Mission and Para-Medic asking about whether Snake saw "My Mother Is a Teenage Spider Queen from Mars", referring to his band "The Spiders from Mars.")
