Which system provides the capability to identify, sequence, and separate aircraft at deployed locations in any weather?

The Deployable Air Traffic-Control and Landing Systems (DATCALS) is designed specifically to support air traffic control in deployed environments. One of its primary functions is to facilitate the identification, sequencing, and separation of aircraft, which is crucial for maintaining safety and efficiency in military aviation, especially in varying weather conditions. This system enables air traffic controllers to manage aircraft movements effectively even when ground-based infrastructure is limited, allowing for operations in remote or forward-deployed locations. Its capability to operate in all weather conditions makes it particularly valuable for military operations, ensuring that aircraft can be effectively managed at any time, under any circumstances. This focus on ensuring cohesive airspace management in diverse environments underscores why DATCALS is the correct choice for the question posed.
