The board of trustees of the fire department pension fund shall have the power to retire from membership in the fire department and thereupon to grant an annual pension to any member of such department, who, while in military, naval or marine service of the United States has become permanently disabled, physically or mentally, so as to be unfit to perform the full duty of his or her employment in such department. Such pension shall not exceed one-half of the annual compensation earned by such member at the time of his or her retirement and shall be paid in like manner as pensions are paid out of the fire department pension fund of such city.
