Operation Storm (Serbo-Croatian: Operacija Oluja/Oпeрaциja Oлуja) was the last major battle of the Croatian War of Independence and a major decisive factor in the outcome of the Bosnian War. It was a decisive victory for the Croatian Army (HV), which attacked across a 630-kilometre (390 mi) front against the Republic of Serbian Krajina (RSK) and a strategic victory of the Army of the Republic of Bosnia and Herzegovina (ARBiH).
