Pigeon Carrier Artillery is a vehicle specialization featured in Battlefield 1 for the Saint-Chamond Field Assault Package. Similar to the singleplayer mission Through Mud and Blood, the player can release a Carrier Pigeon which will result in an artillery strike on the player's location. The tank cannot be operated by the driver from the moment the pigeon is released to the completion of the strike. Passengers may continue to fire their machine guns.
