These elements help an OC/T to integrate capabilities and make decisions that can determine the success of military engagements.
Step-by-step explanation:
An Officer Candidate / Trainee (OC/T) needs to understand the elements of combat power because this knowledge is crucial for planning, executing, and leading military operations effectively. The elements of combat power include maneuver, firepower, protection, leadership, sustainment, information, and mission command. Each element contributes to a unit's overall capability to accomplish its mission, and OC/Ts must be adept at integrating these elements to achieve tactical and operational success.
For example, understanding maneuver allows an OC/T to position forces advantageously on the battlefield, while firepower is essential for delivering lethal and non-lethal effects against the enemy. Protection ensures the preservation of the force, and leadership is vital for inspiring and directing soldiers. Sustainment is necessary for maintaining operations through logistics and support, information is crucial for dominating the informational environment, and mission command is central to exercising authority and direction. Effective integration of these elements can determine the outcome of military engagements.
