The fifth principle states you must not attack which of the following

• A. Medical personnel, facilities, or equipment
• B. Military bases
• C. Enemy supply convoys
• D. Noncombatant contractors

Answer: (A)

The key idea here is the protection of medical personnel and medical resources in conflict. Medical personnel, facilities, and equipment have special protection under the laws of war to ensure care can be provided to the wounded and sick even during hostilities. Attacking them would deprive people of essential medical care and violate international humanitarian norms, making it a prohibited action.

Why this is the best choice: the principle in question specifically directs not to attack those medical assets, keeping lifesaving care available and preserving medical neutrality on the battlefield.

The other options involve targets that can be legitimate military objectives under different rules of engagement (military bases and enemy supply convoys) or civilians, who should be protected but are not what this particular principle specifies.
