The GRAU index (Главное Ракетно-Артиллерийское Управление, Glavnoye Raketno-Artilleriyskoye Upravleniye) is an index by the Main Missile and Artillery Directorate of the Ministry of Defense of the Russian Federation, also known as GRAU. It helps to identify weapons and other things, and is very similar to the NATO reporting index. Firearms on the GRAU index usually have indices starting with 6G, 6P or 6V.
