Step-by-step explanation:
The NCO (Non-commissioned Officer) uses various methods to complement and enhance the knowledge and experience gained through institutional training and education as well as operational assignments. These methods include:
- Field training
- On-the-job training
- Self-study
All of the above are ways that NCOs can improve their skills and adapt to changes throughout their military careers. Through field training, they engage in simulated or actual operational environments to practice and refine the skills needed for combat and leadership. On-the-job training allows NCOs to learn from more experienced personnel in their unit, developing practical skills in a real-world context. Self-study enables independent learning and the pursuit of additional knowledge to stay up-to-date with the latest military strategies and technologies.
