Kargut had several hours to entertain himself while he waited for night fall, So naturally he gravitated to his particular idiom. He was collecting explosives. The guardsmen often had a grenade or two that he could rig up into something exciting. The dozens of guard that they had killed earlier today had plenty for him to tinker with. As the small skirmishes happened around the orky position Kargut was shuffling through collecting explosives, and brutalizing any survivors naturally. As darkness fell he had accomplished his goal to cover their breakout, or more accurately making some hilariously dangerous devices to detonate to cause havoc and mayhem as they left. He placed several around the area they had been occupying earlier today and had left several scattered around the jungle encroaching on the Imperial encirclement. It would be a Roight boom.

Kargut joined the boss and his little crew just as the boss was outlining his plan, Kargut however had a new flourish to his ensemble. He was carrying a many Imperial Guard packs filled with grenades and lasgun power packs rigged to a detonator. If he exploded right now it would more than likely kill everyone present and everything several meters from where he stood. While exciting that wasn't the plan, he would be covering their rear with fire and shrapnel. Making it look like they were attacking the encirclement at a half-dozen different spots all at once so the puny humies didnt know which direction they went until morning at least. 

The Boss singled him out, which was annoying, he was plenty Stelfy and cunnin' he was sure. Honestly he was a Kommando like everyone else, so obviously he was stelfy and cunnin'. It was fine, his plan was extra cunnin' an' brutal, the boss would see that and so would the others. He didn't really tell anyone his plan, he was a mad bomber after all, though his skulking about and the lack of explosions over the last few hours would probably be a good indication that he was up to something. 

As they drew up to the Imperial line the Boss indicated where they were near the humie lines and had everyone get their choppas and silenced shootas, Silenced Shootas! it was blasphemy against Gork... Or possibly Mork, either way a shoota wasnt supposed to be quiet the idea bothered Kargut but he didnt say anything, just laying down one of the imperial packs and twisting a dial that armed the detonator and linked it to the trigger he carried. 

Da Bolta git was all pumped to get to the Imperial lines, Kargut was too, but not quite to the same degree. He couldnt use his bombs because they were all kinds of noisy, and his tank hammer wasn't really much quieter so he would follow everyone else in and leave his presents around so they could make sure the puny humies wouldn't follow them.
