Practice Relating to Rule 72. Poison and Poisoned Weapons
The Dominican Republic’s Military Manual (1980) prohibits the use of poison and poisonous weapons. It tells soldiers:
You may not use poison or poisoning agents such as dead animals, bodies, or defecation to poison any water and food. Of course, you may use non-poisonous methods to destroy military food and water supplies in order to deprive the enemy combatants of their use.
