SSOA meaning in Governmental ?

The South Sudan Opposition Alliance is a coalition of political parties and armed groups in South Sudan that opposed the government of President Salva Kiir. It was formed in February 2018 in Addis Ababa, Ethiopia, by nine groups. In September the alliance acceded to a revised peace deal with the government that also included the main rebel faction, the Sudan People's Liberation Movement-in-Opposition, but some of the member groups disagreed with the decision and split from the alliance. The pro-deal SSOA has experienced continued tension between its members, as well as with the government.
