While not in combat:

4. Do not allow any person below 18 years old to take part in the armed conflict. Children shall be considered as zones of peace and shall enjoy the protection of the State against dangers arising from an armed conflict. Children shall not be recruited or employed by the government forces to perform or engage in activity necessary to and in direct connection with an armed conflict either as a soldier, guide, courier or in a similar capacity which would result in his being identified as an active member of an organized group that is hostile to the government forces.

8. Inform the troops that a child taken in custody by government forces in an area of armed conflict should be informed of his/her constitutional rights and shall be treated humanely. Some of [these] basic rights are “the right to remain silent”, “the right to be presumed innocent until proven guilty”, “the right to be notified of the charge,” “right to counsel”, “right to presence of parents or guardian”, and the “right to confront and cross examine witnesses.”

After an engagement:

8. Immediately transfer child custody to the PNP [Philippine National Police]. In case a child is taken into custody by the AFP [Armed Forces of the Philippines], the military commander concerned shall immediately transfer custody over said child to the nearest stations of the Philippine National Police, preferably to the Child and the Youth Relations (CYRS/CYRO) unit thereof. However, never forget to demand receipt from the PNP.
