What is the function of Mode 2 in the IFF system?

Mode 2 in the Identification Friend or Foe (IFF) system is specifically designated for military use. This mode is utilized primarily to identify military aircraft and differentiate them from potential threats or non-military entities in combat or operational scenarios. The primary goal of Mode 2 is to provide a secure means for friendly forces to recognize each other, minimizing the risk of friendly fire while maximizing situational awareness during military operations.

While other modes within the IFF system serve various purposes, such as civilian identification or general aviation, Mode 2 is strictly tailored for military applications, making it critical in ensuring the safety and efficacy of military missions. Other modes may accommodate civilian and general aviation needs, but they do not overlap with the intended function of Mode 2, which remains solely for military identification and engagement.
