Border guards are officials responsible for monitoring and controlling the movement of people and goods across national borders. Their primary duties include checking identification, inspecting vehicles, and ensuring that laws regarding immigration and customs are followed. They play a crucial role in maintaining national security and preventing illegal activities such as smuggling and human trafficking. In many countries, border guards work in collaboration with other agencies, such as customs officials and immigration officers. They often use technology, including surveillance cameras and scanners, to assist in their work. Training for border guards typically includes law enforcement techniques and knowledge of relevant laws and regulations.
