Unless the context clearly indicates otherwise, as used in this article:
(1) "Deputy sheriff" means any person appointed by a sheriff as his or her deputy whose primary duties as deputy are within the scope of active, general law enforcement and as such is authorized to carry deadly weapons, patrol the highways, perform police functions, make arrests or safeguard prisoners. This definition may not be construed to include any person or persons whose sole duties are the service of civil process and subpoenas as provided in section fourteen, article one, chapter fifty of this code, but the exclusion does not preclude the service of civil process or subpoenas by deputy sheriffs covered by the provisions of this code.
