What does Mode 2 under IFF indicate?

Mode 2 under Identification Friend or Foe (IFF) systems specifically indicates the Unit ID. This mode is designed to provide the identity of a platform as it operates within a specific mission or area. When a military asset engages its IFF system in Mode 2, it transmits a unique identifier that is associated with the unit or organization it belongs to. This identification helps to prevent friendly fire incidents and ensures that command and control environments maintain situational awareness of their own forces.

Understanding the different modes of IFF is crucial for safe operations in a complex battlespace where multiple units and platforms may interact. Each mode serves distinct purposes, which can include identifying the type of mission or determining weapon status, but Mode 2 is specifically focused on Unit ID to fulfill operational needs effectively.
