Upon the request of the town council of any town, duly presented to the superintendent, that a member or members of the division be assigned to duty in that town, the superintendent, in his or her discretion, may assign a member or members of the division to duty in that town and thereupon the superintendent, in his or her judgment, may appoint a member or members of the division in addition to the number of members hereinabove provided for; provided, however, that upon making the request, the town shall agree to pay the salary and expenses of the member or members of the division during the period of such duty in the manner hereinafter specified. Each such additional member of the division shall thereupon become a member of the division of state police, and each member so assigned to duty as aforesaid shall during the period of such duty continue to be a member of the division of state police, but his or her salary and expenses shall be paid by the town requesting that he or she be assigned to duty therein. The superintendent shall have full power at all times to withdraw any member assigned to duty in that town and assign another member to his or her place or to discontinue such duty and to make no assignment to replace.
