Children as young as 11 are being snatched from the streets of Burma and being forced to become soldiers, according to a report.
The boys are taken by people working for the army, or military groups opposed to the government, and are threatened if they make a fuss.
Taken to camps to be trained
They're not allowed to tell their parents where they are going, and are beaten if they try to escape the military camps where they become soldiers.
The report comes from the Human Rights Watch group, who say that as many as 70,000 members of the army in Burma - a country also called Myanmar - are under the age of 18.
Government say there are no child soldiers
And that doesn't include the number of children taken by the groups opposed to the government.
The Burmese government deny the claims, saying it is difficult to understand where the report found the information that 20% of the army are underage children.
