    "notes": "The 2S7 Pion (\"peony\") or Malka is a Soviet self-propelled 203mm heavy artillery. \"2S7\" is its GRAU designation.\n\nIt was identified for the first time in 1975 in the Soviet Army and so was called M-1975 by NATO (the 2S4 Tyulpan also received the M-1975 designation), whereas its official designation is SO-203 (2S7). Its design is based on a T-80 chassis carrying an externally mounted 2A44 203 mm gun on the hull rear. The 203-mm 2S7 Pion (M1975) (2S7/SO-203) is the largest tracked self-propelled gun in the Russian inventory.",
