Myanmar’s Civil War: Who are the Main Combatants?

Myanmar has been embroiled in a devastating civil war for six years. The conflict began after Senior General Min Aung Hlaing led a military coup in 2021, ousting an elected government and detaining key political figures, including Nobel laureate Aung San Suu Kyi. This coup disrupted a fragile democratic transition and sparked nationwide protests, leading to a violent crackdown.
Key Combatants in Myanmar’s Civil War
The civil war features four main groups:
- The Military Regime: Led by Min Aung Hlaing, the military has historically been a dominant force in Myanmar, which has seen continuous conflict since 1948.
- Ethnic Armed Groups: Approximately 20 ethnic groups contest the military’s authority, seeking autonomy or rights that were promised but never fulfilled.
- People’s Defence Force (PDF): Formed after the coup, these resistance groups operate under the shadow government, the National Unity Government (NUG).
- New Resistance Groups: Various local militias and alliances have emerged, driven by a desire for political and ethnic equity.
Impact of the Military’s Tactics
The Myanmar military, deeply entrenched in the country’s socio-political landscape, is estimated to have 150,000 to 250,000 soldiers, bolstered by around 100,000 conscripts. Military operations have intensified, utilizing air power and advanced weaponry sourced from international allies like China and Russia. These efforts have enabled the military to reclaim territory and resources lost to resistance groups.
The People’s Defence Force (PDF)
The PDF emerged as a response to the military’s crackdown on demonstrators. Initially, they were composed of peaceful protesters. However, the violence prompted many to seek military training from ethnic armed groups. They currently face challenges in unifying and maintaining effectiveness. The NUG has reported about 250 PDF battalions, totaling approximately 100,000 personnel.
Ethnic Armed Groups: A Mixed Bag
Ethnic armed groups have inflicted significant damage on the military. Their goals often vary based on historical grievances, financial motives, or external pressures. For instance:
- Kachin Independence Army (KIA): With up to 30,000 troops, it is aligned with broader pro-democracy movements.
- Arakan Army (AA): Positioned in Rakhine State, this group has about 40,000 fighters and seeks governance structures resembling a proto-state.
- Myanmar National Democratic Alliance Army (MNDAA): This group has fluctuated in its support depending on external influences, particularly from China.
Emergence of New Resistance Forces
Beyond the PDF, a range of new resistance groups has emerged. Some, like the Karenni Nationalities Defence Force and the Chin Brotherhood, address ethnic discrimination alongside calls for political change. In 2025, these groups unified into the Spring Revolution Alliance, which boasts around 10,000 fighters.
The Future of the Conflict
Looking ahead, analysts expect Min Aung Hlaing to maintain control over the military. Despite facing resistance, the military may continue to solidify its power through military victories over the next decade. The capacity for opposition forces to regroup and strategize will be crucial. Without significant support and leadership, many PDF battalions are at risk of diminishing strength amidst escalating military offensives.
As Myanmar’s civil war progresses, the dynamics among the military, ethnic groups, and resistance forces remain fluid, with the potential for drastic changes in the near future.
