OG-15V round

Also known as
  • OG-15V

  • OG-15 round
  • 73 mm OG-15 projected grenade
  • ОГ-15В

The OG-15V round is a Soviet-origin 73 mm high-explosive fragmentation projected grenade for the 2A28 Grom low-pressure cannon. It gives BMP-1-family 2A28 installations a dedicated anti-personnel and field-fortification round, distinct from the PG-15V HEAT ammunition that dominated the gun's early loadout.

Variants

Public ammunition references treat OG-15V and OG-15VM as the two basic 73 mm FRAG-HE rounds for the 2A28 gun, separated mainly by projectile explosive-fill details rather than by caliber or firing weapon.

Milzo describes OG-15VM as the second basic 2A28 FRAG-HE round, retaining the same complete-round weight and muzzle velocity while using an OG-15M projectile with a different explosive fill.

STV GROUP and Milzo list OG-15V as a 73 mm HE or FRAG-HE round for the 2A28 Grom, while ZTS describes the 2A28 as a 73 mm semi-automatic gun with a 6-8 round-per-minute technical rate of fire.

Ammunition Family Context

The OG-15V is a short HE-fragmentation round built around the OG-9 projectile and OG-15P propelling charge, so it sits beside PG-15V HEAT ammunition rather than replacing it.

TopicSource-backed detailReader note
Firing gunSTV GROUP and Milzo list OG-15V as 73 mm HE or FRAG-HE ammunition for the 2A28 Grom cannon.The catalog treats the round as a 2A28 munition, not as a standalone conflict weapon.
Projectile and chargeMETIS describes the round as the OG-9 projectile with a GO-2 fuze and OG-15P propulsion charge assembly.This explains why references may alternate between OG-15V, OG-15, OG-9, and projected-grenade terminology.
EffectSTV GROUP and Bulcomers describe the round for use against personnel in the open, trenches, shelters, or brick fortifications.That role is different from the armor-penetration role of the PG-15V HEAT family.
Variant splitMilzo separates OG-15V and OG-15VM by projectile explosive-fill details while keeping them in the same 73 mm FRAG-HE family.The public sources do not justify treating OG-15VM as a separate public conflict-use record here.
