Of the four standard rifle firing positions, which is considered the steadiest?

The prone position is considered the steadiest of the four standard rifle firing positions due to several factors that enhance stability. When in the prone position, a shooter lies flat on their stomach, allowing for maximum contact with the ground. This broad surface area between the body and the ground provides significant support and minimizes movement from wind or other external factors.

Additionally, the body's weight is distributed evenly, which helps to keep the rifle steady during the shot. The hands can also support the rifle against the ground or using sandbags or other equipment to further reduce movement. This position allows for better control of breathing and aiming, significantly increasing accuracy.

The other positions, while useful in different scenarios, do not provide the same level of stability. Sitting and kneeling positions offer some support but allow for more movement and less contact with the ground compared to the prone position. The standing position is the least stable, as it relies solely on the shooter's body and balance, making it more challenging to maintain a steady aim. Thus, the prone position is favored for precise shooting when the conditions allow for it.
