Narrative:

Military X VFR in right traffic to runway 1 to land. Small aircraft Y VFR from south was advised to report 3 mi final, straight-in to runway 1 to land. Military X on a right base to final was cleared to land. Small aircraft Y reported on a 3 mi final was given a landing sequence as #2 to follow military X on a 1 1/2 mi final ahead of you. I did not receive a reply from small aircraft Y to my sequence and I immediately went back and questioned small aircraft Y if he received my sequence. Military X then reported a near-miss with an small aircraft he believed. I advised military X of the position of the reporting small aircraft but military X replied, 'he wasn't there when we saw him.' military X continued inbound and landed, taxied to the terminal ramp and came to the tower. I discussed the occurrence with the flight crew pilot. Small aircraft Y had requested to make a 360 turn on his own, proceeded inbound and landed, taxied to his hangar location. Military X filed an near midair collision report with leesburg FSS that indicates a right turn evasive action was taken. No action filed by small aircraft. At the time of this occurrence, the tower was very busy involving a parachute jump operation and several VFR overflt aircraft in and near the vicinity of the parachute aircraft. The tower was attempting to clear the jump area 7 1/2 mi west of the airport prior to 'jumpers away.' perhaps more 'pro-active' control and more 'positive' position reporting of all aircraft will help in preventing a recurrence.

Title: MIL X HAD NMAC WITH SMA Y IN ATA. SEE AND AVOID CONCEPT.

Narrative: MIL X VFR IN R TFC TO RWY 1 TO LAND. SMA Y VFR FROM S WAS ADVISED TO RPT 3 MI FINAL, STRAIGHT-IN TO RWY 1 TO LAND. MIL X ON A R BASE TO FINAL WAS CLRED TO LAND. SMA Y RPTED ON A 3 MI FINAL WAS GIVEN A LNDG SEQUENCE AS #2 TO FOLLOW MIL X ON A 1 1/2 MI FINAL AHEAD OF YOU. I DID NOT RECEIVE A REPLY FROM SMA Y TO MY SEQUENCE AND I IMMEDIATELY WENT BACK AND QUESTIONED SMA Y IF HE RECEIVED MY SEQUENCE. MIL X THEN RPTED A NEAR-MISS WITH AN SMA HE BELIEVED. I ADVISED MIL X OF THE POS OF THE RPTING SMA BUT MIL X REPLIED, 'HE WASN'T THERE WHEN WE SAW HIM.' MIL X CONTINUED INBOUND AND LANDED, TAXIED TO THE TERMINAL RAMP AND CAME TO THE TWR. I DISCUSSED THE OCCURRENCE WITH THE FLC PLT. SMA Y HAD REQUESTED TO MAKE A 360 TURN ON HIS OWN, PROCEEDED INBOUND AND LANDED, TAXIED TO HIS HANGAR LOCATION. MIL X FILED AN NMAC RPT WITH LEESBURG FSS THAT INDICATES A R TURN EVASIVE ACTION WAS TAKEN. NO ACTION FILED BY SMA. AT THE TIME OF THIS OCCURRENCE, THE TWR WAS VERY BUSY INVOLVING A PARACHUTE JUMP OP AND SEVERAL VFR OVERFLT ACFT IN AND NEAR THE VICINITY OF THE PARACHUTE ACFT. THE TWR WAS ATTEMPTING TO CLR THE JUMP AREA 7 1/2 MI W OF THE ARPT PRIOR TO 'JUMPERS AWAY.' PERHAPS MORE 'PRO-ACTIVE' CTL AND MORE 'POSITIVE' POS RPTING OF ALL ACFT WILL HELP IN PREVENTING A RECURRENCE.
