Practice Relating to Rule 20. Advance Warning
Peru’s IHL Manual (2004) states:
When the tactical situation permits, effective advance warning must be given of attacks which may affect the civilian population (infantry fire to encourage civilians to take shelter, dropping leaflets from a plane, etc.).
The warning should be given in good time so that safety measures can be taken to significantly reduce the harmful effects of armed conflict.
The manual also states:
Only missions compatible with international humanitarian law can be planned.
Missions given to subordinates must include all the relevant details required to ensure respect for international humanitarian law (for example, appropriate preventive … warning measures).
