Military MTR X was on practice ILS approach to runway 3 and requested a circle to runway 36. Small aircraft Y called me for takeoff on runway 18, and he would be southbound. I cleared him for takeoff. MTR X called at final approach fix (about 5.7 mi from the airport). I told MTR X to continue and enter a left base to runway 36. Then I gave him traffic on small aircraft Y 'traffic a small aircraft midfield runway 18 on takeoff'. I saw small aircraft Y enter base to runway 36 about 3 mi southwest. Small aircraft Y was then about 200' AGL. I told small aircraft Y to turn right heading 270 degree. MTR X then turned final to runway 36 about 2 mi south. Small aircraft Y did not acknowledge my previous instructions. I told him again to turn right heading 270 degree. He still did not acknowledge and did not turn. I did not clear MTR X for any low approachs or touch and go. When small aircraft Y did not acknowledge I had to give MTR X a right turn heading 090 degree to avoid a collision. At that point, small aircraft Y was almost to the departure end of runway 18 and MTR X was about 1/2 mi final to runway 36. After the aircraft were clear, I tried to contact small aircraft Y. He acknowledged. He said that he had not heard any of my transmissions. Small aircraft Y had plenty of time to clear the path of MTR X if he had done as I instructed (if he heard me). MTR X knew of the traffic departing the runway. I believe I took all the steps necessary to avoid a near midair. I would have waived MTR X off on base had I known that small aircraft Y was not hearing my transmissions.

Title: SMA CAME IN CLOSE PROX TO OPPOSITE DIRECTION LNDG TRAFFIC. CTLR ISSUED TURNS TO BOTH ACFT.
Narrative: MIL MTR X WAS ON PRACTICE ILS APCH TO RWY 3 AND REQUESTED A CIRCLE TO RWY 36. SMA Y CALLED ME FOR TKOF ON RWY 18, AND HE WOULD BE SBND. I CLRED HIM FOR TKOF. MTR X CALLED AT FINAL APCH FIX (ABOUT 5.7 MI FROM THE ARPT). I TOLD MTR X TO CONTINUE AND ENTER A L BASE TO RWY 36. THEN I GAVE HIM TFC ON SMA Y 'TFC A SMA MIDFIELD RWY 18 ON TKOF'. I SAW SMA Y ENTER BASE TO RWY 36 ABOUT 3 MI SW. SMA Y WAS THEN ABOUT 200' AGL. I TOLD SMA Y TO TURN R HDG 270 DEG. MTR X THEN TURNED FINAL TO RWY 36 ABOUT 2 MI S. SMA Y DID NOT ACKNOWLEDGE MY PREVIOUS INSTRUCTIONS. I TOLD HIM AGAIN TO TURN R HDG 270 DEG. HE STILL DID NOT ACKNOWLEDGE AND DID NOT TURN. I DID NOT CLR MTR X FOR ANY LOW APCHS OR TOUCH AND GO. WHEN SMA Y DID NOT ACKNOWLEDGE I HAD TO GIVE MTR X A R TURN HDG 090 DEG TO AVOID A COLLISION. AT THAT POINT, SMA Y WAS ALMOST TO THE DEP END OF RWY 18 AND MTR X WAS ABOUT 1/2 MI FINAL TO RWY 36. AFTER THE ACFT WERE CLEAR, I TRIED TO CONTACT SMA Y. HE ACKNOWLEDGED. HE SAID THAT HE HAD NOT HEARD ANY OF MY TRANSMISSIONS. SMA Y HAD PLENTY OF TIME TO CLR THE PATH OF MTR X IF HE HAD DONE AS I INSTRUCTED (IF HE HEARD ME). MTR X KNEW OF THE TFC DEPARTING THE RWY. I BELIEVE I TOOK ALL THE STEPS NECESSARY TO AVOID A NEAR MIDAIR. I WOULD HAVE WAIVED MTR X OFF ON BASE HAD I KNOWN THAT SMA Y WAS NOT HEARING MY TRANSMISSIONS.
