A massive gang of bandits, swollen by wanna-be hitmen and a few actual hitmen, descended upon the caravan shortly before the turnoff to Hinckley. As they reached the outer range of their weapons' range, the bandits and less-disciplined hangers-on opened fire on the caravan.
"Forty hostiles, most of them small cars or motorcycles. The larger ones appear to be professional models." Eric's man said, "We're looking at a running fight."
"Shift deployment to the other side. Auxilaries, go hot." Eric said, and he powered up his car's systems to full. The deployment rig shifted to go out on the left side, facing the other side of the divided Interstate, and out Eric went in his road car. No sooner was he outside the rig than he popped loose from the bolts holding his wheels his place and brought the car up to highway speed. He turned his car's turreted guns on a motorcycle trying to paint his rig's backdoor, ripping through its armor shell and exploding the bandit's torso. The bike fell and flipped; the rider's corpse separated and landed in two parts along the shoulder.
The rigs and other auxilaries also quickly cut down the cyclists, as they were fools driving by liquid courage and foolhardy delusions of their own abilities. The small cars, on the other hand, had some skilled men behind their wheels; they were road warriors, experienced raiders, hitmen that actually got a job done, and similar desperate men who hadn't managed to get himself killed- until now.
The front and rear rigs did not shy away from using their tank guns. Multiple cars got wrecked utterly by those cannons directly hitting them or the car next to them, forcing those near that sad sack to lose control and crash into something or someone else- taking them out of the fight. Eric and the other auxilaries roamed as needed up and back alongside the rigs to cover gaps and watch blindspots; targeting weak points in the enemy's armor, focusing down targets when they could, and so on.
The second wave soon collapsed and the handful left broke off and fled the Interstate.
"Let them go." Eric said, "Auxilaries return to base. Start damage assessment and repairs."
Once back in the rig, Eric got on a private link with his man: "The third wave will come in an hour; they'll want to take advantage of what the survivors know before liquidating them."
"No, I don't think we'll get a third. Duluth reports an engagement with some bandits. That's likely the wave."
Eric looked at the report and data. "I concur, having seen that."
"The real hitmen will be there already, working to get on the card and win their way into the main event."
