Which of the following is a major cause of poor marksmanship?

The major cause of poor marksmanship is often attributed to improper technique, lack of practice, and equipment malfunction. Each of these factors directly impacts a shooter’s ability to accurately hit targets.

Improper technique can include poor stance, grip, control, or alignment, all of which compromise the shot's effectiveness. A well-developed technique is critical for maintaining consistency in shooting.

Lack of practice means that shooters do not refine their skills or reinforce good habits. Regular practice is essential for developing muscle memory and becoming proficient.

Equipment malfunction can also severely affect performance. Whether it's a rifle misfiring, sights being misaligned, or issues with ammunition, any failure in the equipment can lead to missed shots, no matter how skilled the shooter might be otherwise.

Considering all these factors together, it is clear why this option is identified as a major cause of poor marksmanship, as they collectively address the fundamental aspects needed for effective shooting.
