In modern battlefields, situational awareness is crucial for military forces to make informed decisions and gain a strategic advantage over their adversaries. Identification Friend or Foe (IFF) technology plays a vital role to achieve this objective by allowing friendly forces to differentiate between friend and foe in real-time. This article explores the evolution and indispensable role of IFF technology in bolstering national security amidst the challenges of modern and complex warfare. IFF systems have significantly advanced over the years, adapting to the ever-changing battlefield dynamics and the emergence of sophisticated threats. This paper delves into the historical development of IFF technology, from its inception during World War II to its current state, characterized by cutting-edge advancements in sensor technologies, data fusion, and artificial intelligence.The system uses various methods such as radar, transponders, and encryption techniques to identify friendly forces and prevent friendly fire incidents. IFF technology has become increasingly important in modern warfare, where asymmetric and non-linear conflicts are the norm. The use of unmanned aerial vehicles (UAVs) and other unmanned systems has further increased the need for effective IFF systems. The absence or failure of IFF technology can have severe consequences, such as fratricide incidents, misidentification of targets, and loss of valuable resources. The use of IFF technology can help enhance the effectiveness and safety of military operations, minimize the risk of friendly fire incidents, and ultimately contribute to the success of the mission as well as safeguarding the national security. The article examines the key components and operational principles of contemporary IFF systems, emphasizing their ability to accurately identify and differentiate between friendly and hostile entities in real-time, thereby reducing the risk of fratricide and enhancing situational awareness on the battlefield. It highlights the importance of interoperability among military forces and the necessity of standardization in IFF protocols to ensure seamless integration and information sharing among diverse platforms and coalition partners.
