In which firing position are both arms supported by your legs?

The sitting position is characterized by both arms being supported by the legs. This position provides a stable platform for shooting, as the legs act as a support structure for the arms, allowing for improved accuracy and control. When sitting, the shooter can maintain a solid posture that enhances steadiness, especially for longer shots or when aiming at small targets. This position can also help reduce fatigue during extended shooting sessions and is often used in various hunting and target shooting scenarios.

While the other options involve different levels of support, neither the standing nor kneeling positions provide the same level of arm support through the legs as seen in the sitting position. The prone position does offer substantial stability but does not involve the arms being supported by the legs, as the shooter is lying down. Hence, the sitting position is the most appropriate answer to the question.
