In high-stakes critical combat environments, soldiers have to operate in complete pin-drop silence. They have to exchange vital information discreetly without making sound/noise while making sure that their positions are still hidden! Traditional means like radio or any general spoken commands can expose positions or prove a bit ineffective and risky amid battlefield noise and electronic interference. Therefore, in such critical situations, soldiers rely on visual signaling systems, standard hand gestures, and body language. It is a better replacement for conventional means, which can be a bit impractical and dangerous. But then this is also constrained by the environment, including poor visibility, physical obstacles in the terrain, and the inherent risk of misinterpretation. Such conditions can cause communication breakdown. To overcome these challenges, this paper presents the prototype for an AI-powered platform, “Tactical Sign Language Communication System” (TSLCS). It represents a military communication system for secure, unambiguous and tamper-free communication while avoiding unauthorised access and any scope of misinterpretation. It recognizes gestures (using deep learning and RNN), secure encryption protocols, and transmission technologies to provide reliable communication among military personnel. It’s a next-generation prototype system created to give soldiers better ways to communicate and work amid the crushing conditions of a hostile battlefield. Its highly developed computer vision and AI technology interprets hand signals, facial expressions and body language. It can function in a variety of lighting and sound conditions, including the dark or places that are too noisy. The system also ensures the security of its data using strong encryption so that no one can hack it. It sends important information like GPS location and updates about team members’ status. Overall, this technology is trying to make teamwork, safety and better decision-making during a mission.
