Which of the following is NOT one of the four fundamentals of marksmanship?

The four fundamentals of marksmanship are key principles that ensure accuracy and consistency when shooting. Among these fundamentals, a steady position, proper aim, and trigger squeeze are foundational elements that a shooter must master.

A steady position involves establishing a stable and comfortable stance that allows for controlled shooting without unnecessary movement. Proper aim refers to aligning the sights of the weapon with the target to increase accuracy. Trigger squeeze is about applying the right amount of pressure to the trigger in a smooth and controlled manner, preventing any jerking that could affect the shot.

In contrast, "constant speed" is not recognized as one of the four fundamentals of marksmanship. While maintaining a rhythm and pace can be essential in certain shooting scenarios, it does not directly relate to the fundamental principles of positioning, aiming, or trigger control. Thus, it stands out as the choice that is not aligned with the established core fundamentals of marksmanship.
