The superintendent may also appoint for each company not more than two chaplains, residing within the State of West Virginia, who shall serve without pay, and who may not be required to perform any duties of members of the department, nor shall any bond be required. The superintendent is authorized to furnish each such chaplain one official uniform, with proper chaplain insignia, to be worn at any ceremonial occasion conducted officially by the department where the presence of a member of the clergy is customary. Such chaplains may be reimbursed by the superintendent for all reasonable and necessary expenses actually incurred in attending such ceremonies.
