Which firing position is characterized by only one arm being braced?

The kneeling firing position is distinguished by the unique way that one arm is braced for support while the other arm is free to operate the firearm. In this position, the shooter places one knee on the ground while the other foot is planted firmly, allowing for a more stable and grounded stance than standing. The arm that is utilized for bracing typically rests on the knee, providing a solid point of support to help stabilize the firearm during aiming and shooting.

This approach helps in maintaining accuracy and control, especially at varying distances. The positioning of the body in the kneeling stance strikes a balance between mobility and stability, making it a favored choice in situations where a quick, yet steady shot is required. In contrast, the other positions, such as prone or standing, do not feature this specific characteristic of only one arm being braced in the same manner.
