Convoys refer to groups of vehicles or ships traveling together for safety or efficiency purposes. There are several synonyms for convoys, including caravans, fleets, processions, columns, motorcades, armadas, and flotillas. These terms are often used interchangeably, but each carries a slightly different nuance. For example, a caravan typically refers to a group of travelers journeying together across land, while an armada refers to a large fleet of warships. In military contexts, convoys may also be referred to as formations, battalions or squads. Regardless of the term used, the idea is the same: a group of vehicles or ships traveling together for mutual support and protection.
