A convoy is a group of vehicles or ships traveling together for mutual support and protection. Convoys are often used in military operations to safeguard troops and supplies from enemy attacks. They can also be seen in civilian contexts, such as during natural disasters, where groups of vehicles travel together to ensure safety and provide assistance. In maritime contexts, convoys help protect merchant ships from piracy and other threats while crossing oceans. The practice dates back centuries and has evolved with technology, including the use of radar and communication systems to enhance coordination among the vessels in the convoy.
