Narrative:

ZLA called our traffic at 10 O'clock 5 mi, however, altitude and direction were unreadable. We asked to verify the traffic was level at 16500 ft and were informed it was 16500 ft climbing. We then spotted traffic in a right turn at 10-11 O'clock. Appeared to be turning swbound and converging. We then immediately initiated descent. Aircraft passed overhead with approximately 500 ft vertical separation. We were informed our traffic had visual with us, however, did not appear to attempt any evasive action. Supplemental information from acn 258153: we saw the traffic, but were unable to see which way he was turning and if he was climbing or not. The other aircraft rolled out on a heading that would have resulted in colliding with us. 'Military call sign' also said they had us in sight. Since 'military call sign' had us in sight, why did that idiot roll out on a collision course?

Title: AN ACR LTT AND A MIL HVT HAD AN NMAC.

Narrative: ZLA CALLED OUR TFC AT 10 O'CLOCK 5 MI, HOWEVER, ALT AND DIRECTION WERE UNREADABLE. WE ASKED TO VERIFY THE TFC WAS LEVEL AT 16500 FT AND WERE INFORMED IT WAS 16500 FT CLBING. WE THEN SPOTTED TFC IN A R TURN AT 10-11 O'CLOCK. APPEARED TO BE TURNING SWBOUND AND CONVERGING. WE THEN IMMEDIATELY INITIATED DSCNT. ACFT PASSED OVERHEAD WITH APPROX 500 FT VERT SEPARATION. WE WERE INFORMED OUR TFC HAD VISUAL WITH US, HOWEVER, DID NOT APPEAR TO ATTEMPT ANY EVASIVE ACTION. SUPPLEMENTAL INFO FROM ACN 258153: WE SAW THE TFC, BUT WERE UNABLE TO SEE WHICH WAY HE WAS TURNING AND IF HE WAS CLBING OR NOT. THE OTHER ACFT ROLLED OUT ON A HDG THAT WOULD HAVE RESULTED IN COLLIDING WITH US. 'MIL CALL SIGN' ALSO SAID THEY HAD US IN SIGHT. SINCE 'MIL CALL SIGN' HAD US IN SIGHT, WHY DID THAT IDIOT ROLL OUT ON A COLLISION COURSE?
