Strategic Defense Coalition

"Bring pride to our nation."

- SDC announcer when beginning match.

The Strategic Defense Coalition, or SDC, is a faction in Call of Duty: Black Ops II. They are an East Asian Chinese-led strategic military alliance. This is one of the largest military alliances in the world during the Second Cold War after NATO.

Depending on how the player performs in the Strike Force missions, Russia, India, Afghanistan and Iran may become members or they will ally with JSOC and join the fight against Raul Menendez.

If the player succeeds in all of the Strike Force missions, the SDC will ally with JSOC and they will send their drones to defend the U.S.S. Barack Obama from Menendez's drone attacks in the mission "Odysseus" and will also send elite troops to eliminate Cordis Die mercenary snipers in the final mission "Judgment Day."

If the player fails in one or all of the Strike Force missions, the SDC will invade Russia and joins the coalition. With this, the Chinese Army will be under Chairman Zhao's orders and Premier Chen can't support the JSOC and their allies and he will be mad during the introduction cutscene of "Cordis Die" and blame the Americans for the drone invasion, which resulted of having a bad relationship with China.

Judging by the holographic map in the briefing before the start of the Strike Force mission, SDC has a considerable amount of members from different countries. Section also stated that if Russia joined the SDC, they would be the single largest military alliance on the planet.
