3OF50 active-rocket projectile

The 3OF50 active-rocket projectile is a Soviet-origin 120 mm rocket-assisted high-explosive fragmentation round used in the Nona family’s longer-range fire-support role. Open references identify it as a 3OF50 HE-frag RAP projectile with a pre-engraved driving band and a separate rocket motor, and VPK says the 2S9 Nona fires it to extend range to about 12 km.
