Narrative:
Small aircraft X on practice ILS approach. I cleared small aircraft X for low approach. Make map and right turn heading 180 prior to runway threshold. Traffic in pattern runway 22. I cleared military Y for takeoff runway 22, straight out departure. I then went to sequence aircraft for runway 22 pattern when I turned to check on small aircraft X. Aircraft was well past the runway threshold, turning toward runway 22 upwind traffic. I issued to both aircraft. Military Y had traffic in sight and I observed military Y descend to avoid traffic.

Narrative: SMA X ON PRACTICE ILS APCH. I CLRED SMA X FOR LOW APCH. MAKE MAP AND R TURN HDG 180 PRIOR TO RWY THRESHOLD. TFC IN PATTERN RWY 22. I CLRED MIL Y FOR TKOF RWY 22, STRAIGHT OUT DEP. I THEN WENT TO SEQUENCE ACFT FOR RWY 22 PATTERN WHEN I TURNED TO CHK ON SMA X. ACFT WAS WELL PAST THE RWY THRESHOLD, TURNING TOWARD RWY 22 UPWIND TFC. I ISSUED TO BOTH ACFT. MIL Y HAD TFC IN SIGHT AND I OBSERVED MIL Y DSND TO AVOID TFC.
