In fire support terminology, what does "danger close" refer to?

In fire support terminology, "danger close" refers to engaging targets within a specified distance of friendly troops, which is typically considered to be 600 meters. This term is crucial in military operations because it highlights the risk to friendly forces when conducting fire support, such as artillery or air strikes. When operations are conducted within this proximity, there is a higher potential for collateral damage or friendly fire, necessitating careful coordination and communication.

Understanding this term is vital for maintaining the safety of allied personnel while effectively engaging enemy targets. The parameters for what is considered "danger close" can vary depending on the type of munitions used and the tactical situation, but the standard of 600 meters remains a key guideline for infantry squad leaders when coordinating support operations.
