Identify a common error in door gunnery.

Failing to adequately clear the doorway before entry is a common error in door gunnery because it poses significant risks to both the operator and their teammates. When entering a room or through a doorway without proper clearing, there is a high potential for encountering an ambush or being surprised by an adversary that may be lurking just beyond the threshold. Such a mistake can lead to injuries or fatalities since the operator may expose themselves without confirming the area is secure.

In door gunnery, thorough clearing entails using various techniques and strategies to ensure that the area is safe and that any threats are neutralized before entering. This involves assessing visibility, using cover effectively, and ensuring team coordination to handle potential threats. Recognizing and addressing this common error emphasizes the importance of preparation and situational awareness in tactical scenarios.
