S.D. Codified Laws § 41-6-19.7
Any member of the national guard or other reserve component of the armed forces of the United States who was issued an elk, bighorn sheep, or mountain goat license pursuant to § 41-6-19.6, but was ordered into active federal service in the armed forces of the United States before the license could be used, may be issued a replacement license as provided in this section. After the member has been released from active federal service, the member may request and shall be issued the applicable replacement bighorn sheep, mountain goat, or elk license under the same or substantially similar terms and conditions as those under which the original license was issued. The replacement license shall be issued for the hunting season immediately following the member's release from active federal service. However, if the release occurs during the hunting season, the member may choose either to obtain the replacement license for the remainder of the current season or to obtain the replacement license for use during the next succeeding full season. The replacement license expires at the end of the season during which it is used.
