Narrative:

Military aircraft departed runway 36R climbing to 7000 ft runway heading. Aircraft Y was on 3 mi downwind at 6000 ft and drifted over in departure corridor. Missed by 2 mi, 600 ft. Turned aircraft X to the east for avoidance. Supplemental information from acn 607945: inbound aircraft being vectored for a close left downwind to runway 36L. Inbound descending to 6000 ft assigned heading 180 degrees. Departure given runway heading off of runway 36R climbing to 5000 ft initially then to 7000 ft. Arrival said airport in sight and was told to proceed visually to the airport, maintain 6000 ft. Arrival and departure drifted toward each other and traffic was issued. Arrival responded to an 'RA' and climbed to 7000 ft. Departure was given an immediate right turn to 090 degrees and told to maintain 5000 ft. Human performance, arrival controller, bad judgement, not considering strong winds. Bad phraseology. Arrival controller, inattention.

Title: HSV CTLR'S EXPERIENCED LOSS OF SEPARATION BTWN ARR AND DEP AT 6000 FT.

Narrative: MIL ACFT DEPARTED RWY 36R CLBING TO 7000 FT RWY HDG. ACFT Y WAS ON 3 MI DOWNWIND AT 6000 FT AND DRIFTED OVER IN DEP CORRIDOR. MISSED BY 2 MI, 600 FT. TURNED ACFT X TO THE E FOR AVOIDANCE. SUPPLEMENTAL INFO FROM ACN 607945: INBOUND ACFT BEING VECTORED FOR A CLOSE L DOWNWIND TO RWY 36L. INBOUND DSNDING TO 6000 FT ASSIGNED HDG 180 DEGS. DEP GIVEN RWY HDG OFF OF RWY 36R CLBING TO 5000 FT INITIALLY THEN TO 7000 FT. ARR SAID ARPT IN SIGHT AND WAS TOLD TO PROCEED VISUALLY TO THE ARPT, MAINTAIN 6000 FT. ARR AND DEP DRIFTED TOWARD EACH OTHER AND TFC WAS ISSUED. ARR RESPONDED TO AN 'RA' AND CLBED TO 7000 FT. DEP WAS GIVEN AN IMMEDIATE R TURN TO 090 DEGS AND TOLD TO MAINTAIN 5000 FT. HUMAN PERFORMANCE, ARR CTLR, BAD JUDGEMENT, NOT CONSIDERING STRONG WINDS. BAD PHRASEOLOGY. ARR CTLR, INATTENTION.
