The document discusses the history and development of prosthetics for military use. It begins with a brief history of prosthetics and how the needs of injured soldiers helped advance the field. Modern prosthetics can be simple and lightweight or high-tech with microprocessors. Returning soldiers work to adjust to their new prosthetics and regain independence through rehabilitation. Continued research and funding aims to provide soldiers with prosthetics that closely mimic natural limbs and allow them to resume their lives.
