ACR X TCASII RA WITH SAME ALT ASSIGNED MIL Y HAD LTSS. SYS ERROR. EVASIVE ACTION TAKEN.

Narrative

BEFORE THE ALERT ACR X WAS GIVEN A L TURN FOR TFC OF 20 DEGS; THE CTLR ASKED OUR NEW HDG WHICH WAS 220 DEGS. THEN ANOTHER ACFT BEGAN A LONG DISCUSSION WITH THE CTLR ABOUT DEV AROUND DEVELS TWRS AND SOME OTHER INTXN. DURING THIS DISCUSSION WE GOT A TCASII ALERT AT 6 MI AT OUR ALT. BY TIME X GOT TO CTLR WE GOT A TCASII RESOLUTION TO CLB 2000 FPM. THE CTLR WANTED TO TURN US 40 DEGS L AND TO DSND TO 310. ZDV SAID TFC A MIL TRAINER WITH A CALL SIGN OF MIL Y. SUPPLEMENTAL INFO FROM ACN 272747: THE CAPT AND I IMMEDIATELY LOOKED OUT AND PICKED UP THE TFC. IT APPEARED TO BE SLIGHTLY ABOVE US AND HDG STRAIGHT FOR US. SECONDS LATER WE RECEIVED A TCASII RA 'CLB; CLB.' I DISENGAGED THE AUTOPLT AND STARTED A 2000 FPM CLB TO COMPLY. THE RADIO WAS GARBLED. I HEARD '...TURN L 40 DEGS.' I DID NOT REACT IMMEDIATELY BECAUSE I WASN'T SURE THAT WAS FOR US. SECONDS LATER THE CAPT SAID 'L 40 DEGS; DSND!' I TURNED AND DSNDED IMMEDIATELY AND LOOKED OUT TO SEE THE OTHER ACFT TURNING RIGHT INTO US. BY THIS TIME THE ACFT SHOWED 2 MI OUT ON THE TCASII. I IMMEDIATELY ROLLED OUT AND PULLED BACK ON THE YOKE TO BREAK THE DSCNT AND START A CLB. I PULLED HARD ENOUGH TO GET INTO MACH BUFFET. WE WERE AT ABOUT 34600 FT AT THIS TIME. (AT THIS TIME; THE TFC PASSED 500-1000 FT DIRECTLY BENEATH US.) I ASKED THE CTLR TO MARK THE TAPE. IF YOU'VE GOT A VISUAL ON YOUR TFC; KEEP IT. I WAS INSIDE AND OUT AND ALMOST MISSED YANKING ON THE YOKE TO PREVENT THE MIDAIR. QUESTION A CTLR WHO GIVES YOU MANEUVERS OPPOSITE TO WHAT SHOULD BE CORRECT (TCASII SHOWED A CLB DURING THE ENTIRE INCIDENT). WE MAY HAVE INADVERTENTLY DSNDED INTO THE OTHER ACFT WHILE HE WAS FOLLOWING AN RA. SUPPLEMENTAL INFO FROM ACN 272872: MIL Y ON A CEL NAV CLRNC WHEN REACHING A FLT PLANNED TURN POINT; WE EXECUTED THE PLANNED 90 DEG TURN AND IMMEDIATELY BECAME A CONFLICT WITH ACR X DC-9. WE WERE UNABLE TO ADVISE ZDV PRIOR TO OUR TURN DUE TO RADIO TFC. WE STARTED AN IMMEDIATE DSCNT TO AVOID THE TFC. THE DC-9 TFC PASSED ABOVE AND TO THE R WITH OVER 1500 FT SEPARATION.
