AR-ROG.

This is coolbert:

A hand grenade as intended for and most effective in the urban warfare environment?

As favored and used by the Chechen in their two wars with the Russian?

Thanks to the tip as seen in a You Tube video.

"HE-FRAG Compact Defensive Hand Grenade AR-ROG with DVM Fuze"

"AR-ROG is HE Hand Grenade with Pre-fragmented splinters, intended for defensive close combat. The grenade features compact dimensions and low weight, twice less that of conventional grenades. The incorporation of powerful explosive RDX and pre-fragmented elements ensures the grenade more than 500 splinters within the lethal radius of 7m."

"The AR-ROG grenade is completed with DVM fuze, providing burst of the grenade within 3.2 to 4 sec. from releasing the safety lever. The AR RO Grenade is safe during transportation, storage and service handling and ensures reliable performance in all weather conditions."

That AR-ROG: Length: 110 mm, 4 1/3 inches.  Weight: .25 kg, 1/2 pound.

Military-Operations-Urban-Terrain [MOUT] require a lot of grenades to clear rooms. You can carry twice the load of these AR-ROG for the same weight as a conventional grenade. That is an advantage. Blast too more effective while less collateral damage occurring.
