Flight crew of a cpr 1125 astra jet took evasive action to avoid a military C5 crossing in front of them at the same altitude during arrival vectors 10 mi north of the airport at 6000 ft. After issuing an altitude and heading change, the approach controller subsequently created another conflict when issuing a vector and altitude change which was amended after the crew advised of another potential conflict.

Narrative:
Approach vectors of 250 degrees at 6000 ft directly conflicted with a C5 heading approximately 180 degrees at 6000 ft. We took evasive maneuvers and called approach. He told us to go to 7000 ft and when clear turn to 180 degrees and go down to 6000 ft. The C5 had turned to approximately 250 degrees (on vectors I think), so approach's vector turned and descended us directly towards the C5 again. We notified approach and he had us maintain 6500 ft. Evidently there was a loss of situational awareness in the approach control. Everyone needs to stay alert. I talked with supervisor at approach control and he said it was an 'operational error.'
Original NASA ASRS Text
Title: FLC OF A CPR 1125 ASTRA JET TOOK EVASIVE ACTION TO AVOID A MIL C5 XING IN FRONT OF THEM AT THE SAME ALT DURING ARR VECTORS 10 MI N OF THE ARPT AT 6000 FT. AFTER ISSUING AN ALT AND HDG CHANGE, THE APCH CTLR SUBSEQUENTLY CREATED ANOTHER CONFLICT WHEN ISSUING A VECTOR AND ALT CHANGE WHICH WAS AMENDED AFTER THE CREW ADVISED OF ANOTHER POTENTIAL CONFLICT.
Narrative: APCH VECTORS OF 250 DEGS AT 6000 FT DIRECTLY CONFLICTED WITH A C5 HDG APPROX 180 DEGS AT 6000 FT. WE TOOK EVASIVE MANEUVERS AND CALLED APCH. HE TOLD US TO GO TO 7000 FT AND WHEN CLR TURN TO 180 DEGS AND GO DOWN TO 6000 FT. THE C5 HAD TURNED TO APPROX 250 DEGS (ON VECTORS I THINK), SO APCH'S VECTOR TURNED AND DSNDED US DIRECTLY TOWARDS THE C5 AGAIN. WE NOTIFIED APCH AND HE HAD US MAINTAIN 6500 FT. EVIDENTLY THERE WAS A LOSS OF SITUATIONAL AWARENESS IN THE APCH CTL. EVERYONE NEEDS TO STAY ALERT. I TALKED WITH SUPVR AT APCH CTL AND HE SAID IT WAS AN 'OPERROR.'
