Practice Relating to Rule 30. Persons and Objects Displaying the Distinctive Emblem
Zimbabwe’s Code of Conduct for Combatants (1993), under the heading “Combat rules”, states:
Combatants:
Respect these signs [i.e. the red cross, red crescent and red crystal]!
which protect:
- wounded and sick
- medical staff and Red Cross/Red Crescent/Red Crystal personnel
- ambulances and Red Cross/Red Crescent/Red Crystal transports
- hospital, first-aid posts and Red Cross/Red Crescent/Red Crystal premises.

The Code of Conduct further states: “Special protection is to be given to Red Cross/Red Crescent/Red Crystal personnel, buildings and equipment.”

Under the heading “Distinctive signs”, the Code of Conduct shows an image of a building with a red cross on a white ground and states: “Leave these buildings [and] establishments … untouched”.
