Frigid Fracas by Mack Reynolds

It was the common practice among Category Military mercenaries of highest rank to maintain skeleton staffs between those periods when they were under hire by corporations or unions. That of Marshal Stonewall Cogswell was one of the most complete, he habitually keeping upward of a hundred officers in his private uniform. It paid off, for with such a skeleton force of highly skilled professionals as a cadre, the marshal could enlist veterans for his rank and file and whip together a trained fighting force in a fantastically short period.

And nothing was so of the essence as time, in the present Category Military. For when two corporations sued for permission to meet on a military reservation for trial by combat to settle their commercial differences, the sums involved were staggering. Joe Mauser had been correct in saying that the fracas had grown, even in his memory, from skirmishes involving a company or two of men, to full fledged battles with a division or even more on either side, forty thousand men at each other's throats.
