The VO-832DU is a Bulgarian 82 mm high-explosive mortar bomb sold by Arcus JSC for 82 mm smooth-bore mortars, including the 2B14 Podnos. The record also tracks closely related O-832DU-family evidence: NARA/DVIDS documents Bulgarian O-832DU rounds in an 2003 Iraq War weapons cache, while GICHD's Ukraine ordnance guide identifies the improved 53-O-832DU version in its 82 mm O-832 entry.

This is a family-level page: 81 mm L16/M252/M252A1/F2-type systems and 82 mm Soviet/Russian-pattern systems such as 2B14 and 2B24 share a medium-mortar battlefield role but are not interchangeable hardware.
