Myanmar’s military, the Tatmadaw, has been the dominant institution in the country for most of its post-independence history. After decades of military rule, it began the shift to a semi-civilian government. A new generation of leaders in the military and in government pushed the transition far further and much faster than anyone could have imagined. Major questions remain, however, about the Tatmadaw’s intentions, its ongoing involvement in politics and the economy, and whether and within what timeframe it will accept to be brought under civilian control. Transforming from an all-powerful military to one that accepts democratic constraints on its power will be an enormous challenge.
