Narrative:

Military X, a flight of 4 fgt's, were recovering from warning area W-157A en route to dobbins AFB (mge), GA. A radar handoff was received from 'sealord' (facsfac jax, mru located at NAS jacksonville) with the military X at and assigned FL370. Air carrier Y was sbound on J79 at FL350. The sealord controller issued (in error) descent to FL350 to military X, and military X exited the warning area at FL350 approximately 10 NM converging with air carrier Y. I at first believed that military X mode C was incorrect, but issued traffic information and a turn to 270 degrees to air carrier Y until communications were established with military X. When military X checked on frequency I issued 'immediate' climb to FL370, as conflict alert had activated when the aircraft were approximately 6 NM apart and closing. Unfortunately, all mode C information on both targets was lost until after the aircraft passed each other. I estimate that the closest proximity was 2-3 mi at the same altitude and closing when 'immediate' instructions were issued to military X. The air carrier Y aircraft was TCASII equipped, but whether an alert was activated to the flight crew is unknown but the crew did question why the military aircraft were at his altitude. A military facility deviation has been filed.

Title: MIL X ASSIGNED SAME ALT AS ACR Y HAD LTSS. SYS ERROR.

Narrative: MIL X, A FLT OF 4 FGT'S, WERE RECOVERING FROM WARNING AREA W-157A ENRTE TO DOBBINS AFB (MGE), GA. A RADAR HDOF WAS RECEIVED FROM 'SEALORD' (FACSFAC JAX, MRU LOCATED AT NAS JACKSONVILLE) WITH THE MIL X AT AND ASSIGNED FL370. ACR Y WAS SBOUND ON J79 AT FL350. THE SEALORD CTLR ISSUED (IN ERROR) DSCNT TO FL350 TO MIL X, AND MIL X EXITED THE WARNING AREA AT FL350 APPROX 10 NM CONVERGING WITH ACR Y. I AT FIRST BELIEVED THAT MIL X MODE C WAS INCORRECT, BUT ISSUED TFC INFO AND A TURN TO 270 DEGS TO ACR Y UNTIL COMS WERE ESTABLISHED WITH MIL X. WHEN MIL X CHKED ON FREQ I ISSUED 'IMMEDIATE' CLB TO FL370, AS CONFLICT ALERT HAD ACTIVATED WHEN THE ACFT WERE APPROX 6 NM APART AND CLOSING. UNFORTUNATELY, ALL MODE C INFO ON BOTH TARGETS WAS LOST UNTIL AFTER THE ACFT PASSED EACH OTHER. I ESTIMATE THAT THE CLOSEST PROX WAS 2-3 MI AT THE SAME ALT AND CLOSING WHEN 'IMMEDIATE' INSTRUCTIONS WERE ISSUED TO MIL X. THE ACR Y ACFT WAS TCASII EQUIPPED, BUT WHETHER AN ALERT WAS ACTIVATED TO THE FLC IS UNKNOWN BUT THE CREW DID QUESTION WHY THE MIL ACFT WERE AT HIS ALT. A MIL FACILITY DEV HAS BEEN FILED.
