The Chindwin River ambushes are a series of ambushes conducted by the People's Defense Force (PDF) and local anti-junta militias against Myanmar Army supply boats traveling across the Chindwin. Initially, anti-junta forces relied on single-shot Tumi guns to ambush the boats.[1] As the Myanmar civil war raged on, the PDF and allied local militias would eventually use automatic weapons and explosives to attack the boats.[2][3][4][5][6]
