(a) No medal of honor, Coast Guard cross, distinguished service medal, silver star medal, distinguished flying cross, Coast Guard medal, or bar, emblem, or insignia in lieu thereof may be awarded to an individual unless—(1) the award is made within five years after the date of the deed or service justifying the award;
(2) a statement setting forth the deed or distinguished service and recommending official recognition of it was made by his superior through official channels within three years from the date of that deed or termination of the service.
(b) If the Secretary determines that—(1) a statement setting forth the deed or distinguished service and recommending official recognition of it was made by the individual’s superior through official channels within three years from the date of that deed or termination of the service and was supported by sufficient evidence within that time; and
