The Dark Energy Survey Supernova program (DES SN) will discover approximately 3500 Type Ia supernovae with well-sampled multi-color light curves in the redshift range 0.2 < z < 1.2 over its five year duration. The large field of view and high z-band sensitivity of the Dark Energy Camera, combined with the precision photometry of DES and an improved handling of systematic uncertainties will allow DES SN to provide the strongest constraints on supernova cosmology to date. One of the main challenges for DES SN will be accurate classification of such a large number of faint transients. I describe the unique spectroscopic follow-up strategy that we are employing, with emphasis on the 100 night, survey-status program at AAT which began in September. I present preliminary supernova results obtained from the DES Science Verification period and the beginning of DES Year 1.
