RGN hand grenade

The RGN hand grenade (Russian: Ручная Граната Наступательная, romanized: Ruchnaya Granata Nastupatel'naya, lit. 'Hand Grenade Offensive') is an offensive Soviet blast hand grenade introduced during the Soviet–Afghan War alongside the RGO to replace the earlier F-1, RG-42, and RGD-5 hand grenades which proved to be inadequate in the mountainous terrain of Afghanistan.
