Kurt was far more occupied with the current nature of the situation than any sorts of material gains. He saw their survival as a unit as the overall goal here, whether they succeeded in the mission or not, dead soldiers made for failed orders as it was. As such, he spent most of his time gazing out over the likely routes where enemies could well be coming from. Surprisingly many, though there seemed to be ample enough cover...maybe not for the super mutant, but enough nonetheless. 

Clutching his rifle, he listed in to the conversation between the rigger and the, ex-ranger? Kurt still needed to ask the woman in some way if she was still an actual member of what remained of the NCR or not, he had no great love for the nation but they could be useful in a pinch. His vigil done for the time being, he walked with all the grace of a stiffened robot to the caravan, stopping just short when he saw the situation between the ranger and rigger go from slightly agitated to seeming hostilities. 

Kurt hadn't wanted to pick sides, they were after all supposed to be on the [i]same side[/i] as it currently was. Perhaps these people were weak? Maybe they were suffering from some sort of disease. He would have to test them for either once this event blew over. He certainly couldn't tell why they were fighting.

Keeping the rifle in hand and ready, he kept watch as the two had their moment.
