Design

The SOHG grenade is based on the HGO-115 non-modular offensive model hand-grenade.^[1]

SOHG grenades are "stackable", meaning up to three can be configured^[2] and connected to increase blast power to provide overpressuring effects,^[3] while using the same fuze.

The base grenade has a non-removable, 3.5 second fuse and a body encasing .25 pounds (110 g) of high explosive, so three connected grenades can have up to .75 lb (340 g) of blast force.^[4][5][6]

Adoption

In 2010, US SOCOM began fielding SOHG grenades under the designation Mk 21 Mod 0.^[7]
