C4ISR
C4ISR stands for Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance. It's a term commonly used in defense and military jobs to describe the systems that help military forces gather information, communicate, and make decisions. Think of it as the nervous system of modern military operations - it's how military units share information, coordinate actions, and understand what's happening on the battlefield. When you see this term in a resume, it usually means the person has experience working with military communication systems, data analysis tools, or surveillance equipment.
