Extra charged stikkbombs

“Grimruk ripped a wood-handle stikkbomb from his belt, nodding for the kommando with him to do the same. The two orks smacked the heads of the grenades against the wall of the bunker, then cast the activated explosives through the firing slits for the bolters. The walls of the bunker failed to restrain the fury of the blast. In a shower of flame and debris, the bunker virtually collapsed in upon itself. The two orks who had attacked the fortification were thrown like rag dolls, smashing into the ground a dozen metres away. Grimruk painfully lifted himself back onto his feet, one arm hanging limp and broken at his side. The kommando with him had fared even worse, the force of the explosion impaling his body on one of the tank-traps. The kaptain glowered at the mutilated ork, then scowled at the smoking wreckage of the bunker. He’d need to talk to the mekboyz about how much punch they packed into their stikkbombz. Grimruk shook his head to clear the ringing from his ears. He stared at the ground, looking for the peaked cap that had been blown off by the explosion. He stopped looking when Wizgrot appeared beside him, timidly handing the battered hat to the ork. Grimruk snatched the hat from the gretchin and stomped towards the wrecked bunker. Now that the heavy bolters were quiet, other kommandos were breaking cover to close upon the destroyed objective. Grimruk pushed his way through the press of orks, determined to be the first to see whatever was left. The bunker was a shambles, twisted supports protruding at crazy angles from shattered blocks of processed stone. Here and there the mangled wreck of a soldier jutted out from the jumbled mess. Grimruk snorted contemptuously as he looked at the walls. The stikkbombz had blasted them to bits, like they were nothing but paper. Maybe he’d suggest the mekboyz keep making the grenades the way they were. Provided of course that they let him know first.”
