The Tatmadaw, also known as the Sit-Tat, is the armed forces of Myanmar (formerly Burma). It is administered by the Ministry of Defence and composed of the Myanmar Army, the Myanmar Navy and the Myanmar Air Force. Auxiliary services include the Myanmar Police Force, the Border Guard Forces, the Myanmar Coast Guard, and the People's Militia Units. Since independence in 1948, the Tatmadaw has faced significant ethnic insurgencies, especially in Chin, Kachin, Kayin, Kayah, and Shan states. General Ne Win took control of the country in a 1962 coup d'état, attempting to build an autarkic society called the Burmese Way to Socialism. Following the violent repression of nationwide protests in 1988, the military agreed to free elections in 1990, but ignored the resulting victory of the National League for Democracy and imprisoned its leader Aung San Suu Kyi. The 1990s also saw the escalation of the conflict involving Buddhists and Rohingya Muslims in Rakhine State due to RSO attacks on the Tatmadaw forces, which saw the Rohingya minority facing oppression and, starting in 2017, genocide.
In 2008, the Tatmadaw again rewrote Myanmar's constitution, installing the pro-junta Union Solidarity and Development Party (USDP) in the 2010 elections, which were boycotted by most opposition groups. Political reforms over the next half-decade culminated in a sweeping NLD victory in the 2015 election; after the USDP lost another election in 2020, the Tatmadaw annulled the election and deposed the civilian government. The Tatmadaw has been widely accused by international organizations of human rights violation and crimes against humanity; including ethnic cleansing, political repression, torture, sexual assault, war crimes, extrajudicial punishments (including summary executions) and massacre of civilians involved in peaceful political demonstrations. The Tatmadaw has long operated as a state within a state.
According to the Constitution of Myanmar, the Tatmadaw is led by the commander-in-chief of Defence Services. Some actions of the Tatmadaw require the approval of the National Defence and Security Council, an eleven-member national security council responsible for security and defence affairs in Myanmar. The president of Myanmar has no command role over the Tatmadaw, though he may work with the NDSC in authorizing military action.
