The issue names Mission Planner's Swarm, Follow the leader, Sequence Swarm, and Follow swarm modes but mentions no file, test, or documentation entry point. Start by locating where these Mission Planner features are documented or exposed, then compare their behavior and document the distinctions. Done means the four modes have a clear explanation in an appropriate project document.
