roll call

Roll call is the calling of the names of people from a list (roll) to determine the presence or absence of the listed people (also know as a register in countries such as the UK). The term applies to the calling itself, to the time moment of this procedure, and to a military signal that announces it (e.g. by a drum). Roll calls are used in places such as classrooms, the military, prisons, law enforcement, and camps. In traditions of some schools, the term Roll Call refers to a general assembly for various daily announcements; see for example the traditions of the Groton School. The Roll Call of Honor is a ceremonial roll call of honorably fallen people or a list of these people.
