DOGS OF WAR!

The Diamond Dogs was a mercenary unit led by Big Boss 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. 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.
