These days, national security is the top concern for every country. Wars are being waged over territory, water, and the title of most powerful country. The army, navy, and air force are the three professional uniformed services that make up a nation's armed forces. The core of any armed force, its soldiers, frequently perish from a lack of access to emergency medical care. Additionally, soldiers on missions or in special operations may become lost in the battlefield and lose communication with the authorities. The system is made up of two units: the base station unit and the soldier's unit. As seen in the illustration below, the soldier's unit can be attached to their jacket. Major mobile is the base station unit. On their mobile device, he or she can view every parameter. Additionally, this project is improved by utilising NODE MCU and IOT technology. Additionally, an LED lamp is used to establish indication at the local setup.
