What is the purpose of GT-IV through GT-VI?

The purpose of GT-IV through GT-VI is to build on individual skills. These stages are designed to enhance and refine the skills that the trainees have already developed, allowing them to perform more complex tasks and drills with increasing proficiency. Each stage focuses on different aspects of door gunnery practice, ensuring that individuals become more adept in their capabilities. This progression is essential for developing the necessary expertise and confidence before moving on to more advanced training scenarios or practical applications, such as live fire exercises.

Building on individual skills is crucial in a training context as it lays the groundwork for subsequent competencies and ensures that each trainee reaches a solid level of proficiency before taking on more demanding challenges. This foundational development is vital in preparing individuals for real-world applications where skill proficiency can significantly impact teamwork and mission success.
