(c) Any member of any such department whose service has been interrupted by duty with the armed forces of the United States as provided in section twenty-seven of this article prior to July 1, 1981, shall be eligible for retirement pension benefits immediately upon retirement, regardless of the member's age, if the member shall otherwise be eligible for such retirement pension benefits. In no event are provisions of this subsection to be interpreted to permit retirement before age fifty unless the interruption of the member's service by duty with the armed forces of the United States actually occurred before July 1, 1981. The amendment made to this subsection during the 2013 regular session of the Legislature is not for the purpose of changing the existing law regarding benefits provided to veterans for military service prior to July 1, 1981, but to further clarify that the provisions of this section and any previous enactments of this section do not make a member eligible for retirement before age fifty for a member's service with the armed forces of the United States after July 1, 1981. Any member or previously retired member of any such department who has served in active duty with the armed forces of the United States as described in section twenty-seven of this article, whether prior to or subsequent to becoming a member of a paid police or fire department covered by the provisions of this article, shall receive, in addition to the sixty percent authorized in subsection (a) of this section and the additional percent credit
authorized in subsection (b) of this section, one additional percent for each year so served in active military duty, up to a maximum of four additional percent. In no event, however, may the total benefit granted to any member exceed seventy-five percent of the member's annual average salary calculated in accordance with subsection (a) of this section.
