Narrative:
Controller called mlt traffic at 0130 O'clock position, 5 mi climbing to FL280. We were tracking on TCASII and were looking for visual contact. Informed first officer to be prepared for TCASII RA due to controller asking mlt to confirm leveling at FL280. Due to UHF radio in mlt, we couldn't hear response. TCASII issued TA at approximately 3 1/2 mi. Target 2000 below us climbing rapidly. TCASII issued RA for 'climb' at approximately 2 1/2 mi. Climb initiated from FL290 at approximately 3000 FPM. Traffic continued to close. At approximately 30200, TCASII issued 'monitor vertical speed.' target passed directly under us at a closest point of approach of about 500 ft.

Title: A HIGH PERFORMANCE MIL TRAINER OVERSHOT ITS ALT IN CLB CAUSING AN ACR MLG TO CLB IN RESPONSE TO A TCASII COMMAND.
Narrative: CTLR CALLED MLT TFC AT 0130 O'CLOCK POS, 5 MI CLBING TO FL280. WE WERE TRACKING ON TCASII AND WERE LOOKING FOR VISUAL CONTACT. INFORMED FO TO BE PREPARED FOR TCASII RA DUE TO CTLR ASKING MLT TO CONFIRM LEVELING AT FL280. DUE TO UHF RADIO IN MLT, WE COULDN'T HEAR RESPONSE. TCASII ISSUED TA AT APPROX 3 1/2 MI. TARGET 2000 BELOW US CLBING RAPIDLY. TCASII ISSUED RA FOR 'CLB' AT APPROX 2 1/2 MI. CLB INITIATED FROM FL290 AT APPROX 3000 FPM. TFC CONTINUED TO CLOSE. AT APPROX 30200, TCASII ISSUED 'MONITOR VERT SPD.' TARGET PASSED DIRECTLY UNDER US AT A CLOSEST POINT OF APCH OF ABOUT 500 FT.
