Or rather than being trigger happy they could have higher standards for targeting than even the ICRC suggests. Leave the cook instead of shooting him as a combatant. Shoot to disable rather than kill. Use less lethal weapons even in a real war if appropriate. Deliberately take 90% casualties in order to minimise civilian or even enemy casualties.
