Which of the following is NOT one of the standard shooting positions?

The standard shooting positions include sitting, kneeling, and prone. Each of these positions has specific advantages that contribute to stability and accuracy when aiming and firing a firearm.

Sitting provides a steady base of support and is often used for longer-range shooting because it allows for a good line of sight and control over the firearm. The kneeling position is a transitional stance that provides a balance between mobility and stability, making it effective for various hunting scenarios. The prone position is the most stable of the three, as it allows the shooter to lie flat on the ground, minimizing movement and maximizing accuracy.

On the other hand, leaning is not recognized as a standard shooting position. While shooters might lean against a tree or other support for added stability in certain situations, it does not constitute a formal position within standard shooting practice. Leaning can lead to inconsistent shooting angles and less control, as it relies on external support rather than the shooter's own body mechanics.
