Usage
''Picket'' now refers to a soldier or small unit of soldiers maintaining a watch. This may mean a watch for the enemy, or other types of watch e.g. fire picket. This can be likened to the art of sentry keeping. A staggered picket consists of, for example, two soldiers where one soldier is relieved at a time. This is so that on any given picket one soldier is fresh, having just started the picket, while the other is ready to be relieved. Although each soldier is required to maintain watch for the full duration of a shift, halfway through each shift a new soldier is put on watch.See also
