Current GRAU indices
GRAU indices are of the form ⟨number⟩⟨letter⟩⟨number⟩, sometimes with a further suffix ⟨letter⟩⟨number⟩. They may be followed by a specially assigned codename. For example "2 S 19 Msta-S", the 2S19 Msta self-propelled howitzer, has the index 2S19, without suffix; Msta-S is the codename.
