The 71 migrants - 55 men and 16 women - were found to have landed in Ranong province and were taking a rest near an oil palm plantation at Ban Hin Yai in tambon Jor Por Ror.
They were about to be transported on two trucks to different destinations when the military unit showed up. The drivers of the two trucks managed to escape before the soldiers arrived.
An initial investigation at the Infantry Company 2521 headquarters found the Myanmar migrant workers were brought by boat to Ranong by traffickers. Their destinations were Phuket, Surat Thani, Songkhla and Malaysia.
Those seeking to work in the three Thai provinces had paid 10,000 baht each to the traffickers. Those destined for Malaysia had to pay 20,000 baht each.
They were charged with illegal entry.
