Which rifle firing position provides the least support?

The standing position provides the least support when firing a rifle. This is primarily due to the lack of contact with the ground, which diminishes stability and balance. In this posture, the body is upright, relying solely on the arms and shoulders to hold and aim the rifle. The absence of additional support from the ground or other surfaces makes it more challenging to maintain accuracy, particularly with larger caliber rifles that produce significant recoil.

In contrast, the sitting, kneeling, and prone positions offer varying degrees of support. The sitting position allows for more balance and stability by utilizing the legs and feet, while the kneeling position also creates a lower center of gravity. The prone position is the most stable of all, as it provides maximum contact with the ground, which significantly enhances accuracy and reduces movement during the shot.
