Commonwealth - Vast War

The Commonwealth - Vast War was a major conflict in the Halo 5 clan community involving the Commonwealth, Vast, Naval Command and a conglomerate coalition called the Military Memorial Alliance (MMA). Following ShadowSniper172 's declaration of war on Vast May 13th 2016, TCW's Operation Swift Dawn began, initiating a clan war to eradicate clans deemed "against community values and the meta". On May 15 2016, Vast initiated a successful retaliatory offensive with CW/MMA forces failing to withstand constant assaults. Naval Command would open a second front on June 11 with TCW capitulating on June 16 2016.

The resulting aftermath led to the Vast - Exodus conflict.
