Narrative:
Olk (wolf lake) radar controller was working busy traffic with an unqualified d-side. A 'sting' flight of F16's left fwa approach climbing to FL180 en route to hilltop MOA. The 'sting' route of flight traversed bearz sector arrival corridor without a pointout. The bearz controller descended 2 ord arrival flts to 16000 ft from FL240. Upon noticing the target climbing to FL180, the bearz controller stopped the ord arrs at FL190. 1 aircraft had to climb from 18300 ft back to FL190. Loss of separation and airspace violation were not processed by FAA supervisor. The 'sting' flight was non-standard formation. Approximately separation: 300 ft and 4 mi, instead of 1000 ft and 6 mi.

Title: ZAU CTLR OBSERVES A NON-COORDINATED, CLBING MIL FLT, PENETRATE AN ADJOINING CTL SECTOR AND CONFLICT WITH A DSNDING ACR.
Narrative: OLK (WOLF LAKE) RADAR CTLR WAS WORKING BUSY TFC WITH AN UNQUALIFIED D-SIDE. A 'STING' FLT OF F16'S LEFT FWA APCH CLBING TO FL180 ENRTE TO HILLTOP MOA. THE 'STING' RTE OF FLT TRAVERSED BEARZ SECTOR ARR CORRIDOR WITHOUT A POINTOUT. THE BEARZ CTLR DSNDED 2 ORD ARR FLTS TO 16000 FT FROM FL240. UPON NOTICING THE TARGET CLBING TO FL180, THE BEARZ CTLR STOPPED THE ORD ARRS AT FL190. 1 ACFT HAD TO CLB FROM 18300 FT BACK TO FL190. LOSS OF SEPARATION AND AIRSPACE VIOLATION WERE NOT PROCESSED BY FAA SUPVR. THE 'STING' FLT WAS NON-STANDARD FORMATION. APPROX SEPARATION: 300 FT AND 4 MI, INSTEAD OF 1000 FT AND 6 MI.
