W. Va. Code § 6-3-1a
(c) Members of the reserves shall not serve as law-enforcement officers, nor carry firearms, except that a member of the reserves may carry a firearm approved by the sheriff while acting in the capacity as a reserve deputy sheriff solely for purpose of defense of self or others, if that member has:
(3) Successfully completed a firearms training and certification program equivalent to that provided to officers attending the entry level law-enforcement certification course provided at the West Virginia State Police Academy. The member must thereafter successfully complete an annual firearms qualification course equivalent to that required of certified law-enforcement officers as established by legislative rule. The department may reimburse the member for the cost of the training and requalification.

In addition, the reserves may perform any other duties of a nonlaw-enforcement nature designated by the sheriff or by a deputy sheriff designated and appointed by the sheriff for that purpose: Provided, That a member of the reserves may not aid or assist any law-enforcement officer in enforcing the statutes and laws of this state in any labor trouble or dispute between employer and employee.
