What is the total number of engagements required for an Avenger team leader to perform?

An Avenger team leader is required to complete a total of four engagements to fulfill their training and operational requirements. In this context, the term "engagements" refers to the tasks or operations that the team leader must successfully lead and execute, demonstrating proficiency in their role within the Avenger system. The four engagements are essential for ensuring that the team leader gains adequate experience, familiarizes themselves with the operational aspects of the Avenger system, and develops the necessary leadership skills to effectively guide the team during real-world missions. This structured approach ensures that the team leader is well-prepared for various scenarios they might encounter in the field.
