A battle drill is a type of standard operating procedure used in the training of infantry. Based on commonly encountered scenarios, battle drills are used to establish standardized actions of a team, allowing for a quick collective response without the need for deliberate decision making. Platoons and squads apply fire and maneuver accordingly, requiring leaders to rapidly make decisions and quickly issue brief oral orders.[1] In 1944, Colonel Charles Stacey defined the practice of battle drill as "the reduction of military tactics to bare essentials which are taught to a platoon as a team drill, with clear explanations regarding the objects to be achieved, the principles involved and the individual task of each member of the team."[2]
A US Army publication from 2016 identifies fourteen "essential battle drills that an Infantry platoon and squad must train on to ensure success":[3]
