In Myanmar, since the country’s founding, the Tatmadaw has been heavily involved in domestic politics and the national economy; it ran the country for five decades following a military coup in 1962; prior to the most recent coup in 2021, the military already controlled three key security ministries (Defense, Border, and Home Affairs), one of two vice presidential appointments, 25% of the parliamentary seats, and had a proxy political party, the Union Solidarity and Development Party (USDP); it owns and operates two business conglomerates that have over 100 subsidiaries; the business activities of these conglomerates include banking and insurance, hotels, tourism, jade and ruby mining, timber, construction, real estate, and the production of palm oil, sugar, soap, cement, beverages, drinking water, coal, and gas; some of the companies supply goods and services to the military, such as food, clothing, insurance, and cellphone service; the military also manages a film industry, publishing houses, and television stations

the Tatmadaw's primary operational focus is internal security, and it is conducting counterinsurgency operations against anti-regime forces that launched an armed rebellion following the 2021 coup and an array of ethnic armed groups (EAGs), some of which have considerable military capabilities; as of 2024, the Tatmadaw was reportedly engaged in combat operations in 10 of its 14 regional commands; it has been accused of committing atrocities in the conduct of its campaign against the pro-democracy movement and opposition forces 

the military is supported by pro-government militias; some are integrated within the Tatmadaw’s command structure as Border Guard Forces, which are organized as battalions with a mix of militia forces, EAGs, and government soldiers that are armed, supplied, and paid by the Tatmadaw; other pro-military government militias are not integrated within the Tatmadaw command structure but receive direction and some support from the military and are recognized as government militias; a third type of pro-government militias are small community-based units that are armed, coordinated, and trained by local Tatmadaw forces and activated as needed; the military regime has attempted to raise new militia units to help combat the popular uprising

EAGs have been fighting for self-rule against the Burmese Government since 1948; there are approximately 20 such groups operating in Burma with strengths of a few hundred up to 30,000 estimated fighters; some are organized along military lines with "brigades" and "divisions" and armed with heavy weaponry, including artillery; they control large tracts of the country’s territory, primarily in the border regions; key groups include the United Wa State Army, Karen National Union, Kachin Independence Army, Arakan Army, Ta’ang National Liberation Army, and the Myanmar Nationalities Democratic Alliance Army

the opposition National Unity Government claims its armed wing, the People's Defense Force (PDF), has more than 60,000 fighters loosely organized into battalions; in addition, several EAGs have cooperated with the NUG and supported local PDF groups (2024)
