This grenade was among the first of the German Field-Improvised antitank grenades. When the British tanks arrived on the battlefield in September, 1916, the German forces were not ready to take on such a mechanical monster. There were no target-specific antitank weapons available but the German soldier quickly rose to the task. Taking the separate warheads of two M1916 Stielhandgranates, they were wired to the head of a complete M1916 grenade. The new weapon was a Geballte Ladung [Concentrated Charge], which effectively tripled the explosive charge of a single hand grenade. The new weapon was a bit heavy to use and the bomber had to get close to the approaching tank to properly attack it, but it was effective in penetrating the 6mm (0.24 in) top armor of the Mk I tank. The efficiency of the grenades was enough to force the British to place wire screen frameworks over the tops of their tanks to help deflect incoming grenades. Using a technique that worked to attack barbed wire entanglements, enterprising German soldiers would wire large fishhooks, including improvised version, to the heads of the Geballte Ladung. The hooks would tangle with the screens on top of the tanks and destroy them when the charge detonated.
The data above is for the later-production M1916 Stielhandgranate with the smaller warhead. When in the field, any available high explosive grenades would be used to assemble a concentrated change.
