Four Four Bravo was the call sign of a fifteen-man Sri Lankan Army patrol, deployed in the Jaffna Peninsula on July 23, 1983. The patrol was ambushed and thirteen of its members were killed by the LTTE. This incident sparked the Black July riots and is considered to be the start of the Sri Lankan Civil War.
