OFM round

The OFM round is the 120 mm ammunition label cited in Defense Express's coverage of the Russian 2S40 Floks, where it was reported to reach about 7.2 km from that wheeled gun-mortar. The catalog treats it as a relationship-only ammunition page because its public documentation is centered on the Floks firing relationship rather than a standalone manufacturer profile.
