The emblems of the Red Cross, Red Crescent, and Red Lion and Sun give those authorized to bear them protection against attack in international and non‐international armed conflicts. It is a war crime under the Statute of the International Criminal Court to attack the bearer of a protected emblem. Those entitled to bear the symbol are medical personnel and orderlies, chaplains, Red Cross and Red Crescent workers, employees of aid organizations of neutral states. Emblems also protect buildings, vehicles, ships, and aircraft used for medical purposes.
It is a summary offence under the Geneva Convention Act 1957 to use a red cross emblem unless authorized or on a toy when the emblem must be not more than 1.5 inches across.
