Practice Relating to Rule 15. The Principle of Precautions in Attack
Section C. Feasibility of precautions in attack
At the CDDH, Austria considered that the precautions envisaged in Article 57 of the 1977 Additional Protocol I
could only be taken at a higher level of military command, in other words by the high command. Junior military personnel could not be expected to take all the precautions prescribed, particularly that of ensuring respect for the principle of proportionality during an attack.
