The Cobra Unit was a legendary team of soldiers that were assembled by The Boss in 1942 to combat the Axis Powers. Together it's said that they nearly won the war single handedly. They were later disbanded in 1947, but were reunited in 1964 during Operation Snake Eater, where they fought the Boss's final apprentice, Naked Snake and were all ultimately wiped out by him.
The Pain, The Fear, The End and The Fury all had micro-bombs attached to them that were detonated when they died. Even if they were defeated by wearing down their stamina, the bombs still activate. However, they all (except The End) leave behind special camo where they fell.
