What does PDF stand for in military terminology?

In military terminology, PDF stands for Principle Direction of Fire. This term refers to the designated direction in which a weapon or unit is primarily oriented to provide effective fire coverage during an engagement. Understanding the Principle Direction of Fire is crucial for coordinating attacks, maximizing the effectiveness of firepower, and ensuring that all units are aligned in their efforts during combat operations.

The concept helps in planning and executing missions, especially in situations where crossfire could be a concern or in establishing fields of fire for support elements. By clearly defining this direction, military forces can enhance coordination and reduce the risk of friendly fire, thereby increasing operational effectiveness.
