The department must promulgate regulations necessary to preserve the benefit rights of individuals who volunteer, enlist, or are called or drafted into a branch of the military, naval service, or an organization affiliated with the defense of the United States or this State. These regulations, with respect to these individuals, must supersede an inconsistent provision of Chapters 27 through 41 of this title, but where practicable must secure results reasonably similar to those provided in the analogous provisions of these chapters.
