The term that describes the process of having another soldier observe a firer to check for errors is "coaching." Coaching involves providing real-time feedback and guidance to the shooter, helping them identify and correct any mistakes in their technique, stance, or aiming. This process is crucial for improving marksmanship skills, as it allows the shooter to receive personalized instruction based on their performance.

This collaborative learning approach fosters a supportive environment where soldiers can enhance their shooting proficiency through constructive criticism and encouragement.
