Narrative:

Just departed mlb climbed to 1300 ft MSL on a heading of 020 magnetic course. Inbound for landing at kcof just finished talking to mlb tower for frequency change. Contacted kcof tower. Told them negative ATIS 6.5 mi south of field. They gave us altimeter, runway and wind information. 30 seconds after this transmission, sighted an army small transport above and to the left descending to pafb (kcof). At this time, pilot of army small transport aircraft transmitted on tower frequency 133.75 he came within 100 ft of our aircraft. Both aircraft were on approximately same magnetic course. We did not receive any TA from mlb or kcof. We were looking for traffic constantly. Both aircraft were inbound for landing on runway 20 at kcof. We were ahead, lower and slower than the small transport. After landing, called tower personnel. They told us army small transport was landing on the ILS runway 20. We were VFR talking to tower only. The WX at the time of the incident was VFR 45 scattered with 10 plus mi visibility, wind was 050/10. I believe for future approachs into kcof I will remain 3-5 mi west of extended centerline, thus allowing enough time for approach control or tower to identify upon initial call up.

Title: PVT PLT OF SMA SEL TRAINING ACFT HAD NMAC WITH ANOTHER ACFT ON AN ILS APCH TO THE SAME RWY.

Narrative: JUST DEPARTED MLB CLBED TO 1300 FT MSL ON A HDG OF 020 MAGNETIC COURSE. INBOUND FOR LNDG AT KCOF JUST FINISHED TALKING TO MLB TWR FOR FREQ CHANGE. CONTACTED KCOF TWR. TOLD THEM NEGATIVE ATIS 6.5 MI S OF FIELD. THEY GAVE US ALTIMETER, RWY AND WIND INFO. 30 SECONDS AFTER THIS XMISSION, SIGHTED AN ARMY SMT ABOVE AND TO THE L DSNDING TO PAFB (KCOF). AT THIS TIME, PLT OF ARMY SMT ACFT XMITTED ON TWR FREQ 133.75 HE CAME WITHIN 100 FT OF OUR ACFT. BOTH ACFT WERE ON APPROX SAME MAGNETIC COURSE. WE DID NOT RECEIVE ANY TA FROM MLB OR KCOF. WE WERE LOOKING FOR TFC CONSTANTLY. BOTH ACFT WERE INBOUND FOR LNDG ON RWY 20 AT KCOF. WE WERE AHEAD, LOWER AND SLOWER THAN THE SMT. AFTER LNDG, CALLED TWR PERSONNEL. THEY TOLD US ARMY SMT WAS LNDG ON THE ILS RWY 20. WE WERE VFR TALKING TO TWR ONLY. THE WX AT THE TIME OF THE INCIDENT WAS VFR 45 SCATTERED WITH 10 PLUS MI VISIBILITY, WIND WAS 050/10. I BELIEVE FOR FUTURE APCHS INTO KCOF I WILL REMAIN 3-5 MI W OF EXTENDED CTRLINE, THUS ALLOWING ENOUGH TIME FOR APCH CTL OR TWR TO IDENT UPON INITIAL CALL UP.
