Narrative

IN CRUISE ON A FLT FROM SLC TO PHX AT FL250 AND 35 NM N OF DRK ON J-11; WE RECEIVED A TCASII 'TA.' THE TA SHOWED AT ABOUT 10 O'CLOCK POS; 5 MI 'PLUS 07' (700 FT) ABOVE OUR ALT AND DSNDING; THE 'PLUS 06;' ETC; BECOMING AN RA ALERT WITH 'CLB; CLB.' I IMMEDIATELY BEGIN A CLB AND THE FO TOLD ZLA THAT WE WERE CLBING FROM AN RA TCASII WARNING; AND THEN AS THE RA BECAME CLOSER AT 'ZERO ZERO' ALT DIFFERENCE; I BEGAN A R TURN. I HAD PREVIOUSLY SWITCHED THE TCASII TO THE 5 MI RANGE; AND WE WATCHED THE TARGET PASS WITHIN A MI BEHIND US AND SLIGHTLY BELOW US. OUR CLBING R TURN THEN GAVE US ADDITIONAL TA WITH ACFT AT FL270. WE REVERSED OUR CLB TO A DSCNT AND BACK TO J-11 AFTER 1ST TARGET PASSED; AND OTHER TA'S RECEIVED. WE HEARD THE CTR CTLR TELL A 'MIL Y' CALL SIGN THAT IT WAS NOT CLRED BELOW FL260. FROM PREVIOUS COMS OVERHEARD ON CTR FREQ; A FLT OF 2-F-16'S AS 'MIL Y' HAD A MALFUNCTION ON 1 OF THE ACFT. ALTHOUGH THE F-16'S WERE ON ANOTHER FREQ (ASSUMED UHF) WE HEARD CTR ASK IF THEY WANTED TO DECLARE AN EMER; WHICH THEY APPARENTLY DIDN'T; BUT WERE GIVEN CLRNC TO FL260. SEVERAL MIN LATER; WE RECEIVED THE 1ST TA ALERT.
