Narrative:

We were level at our assigned altitude of FL300. We were about 30NM due west of hnn. Our planned final was FL360. Based on ride conditions and reports I had requested FL280 as a temporary final with indianapolis center. My request was for FL280 was denied because an MOA below was active and its ceiling was FL290. A couple of minutes later the first officer; the flying pilot; saw two military fighters maneuvering to the right of our position below our altitude. He lost visual contact in less than a minute. Nearly two minutes later we received a TA for an aircraft 1500 feet directly below us. TCAS indicated the target was climbing and immediately went to RA mode. What appeared to be a military fighter; which was confirmed by center; came into view and was headed southwest and immediately made a climbing left turn and was headed back northeast towards us. TCAS issued climb instructions to avoid collision. A second fighter came into view in chase of the first. The trailing aircraft was to our right and lower; but TCAS was not 'painting' him. About 2 seconds later the lead fighter climbed to our altitude and TCAS issued descent instructions (within 2 seconds of the climb instructions). At this point the lead fighter was about 1 mile in front of us and 200 feet above our altitude. The second fighter turned to the northeast and flew directly underneath us. The trailing fighter came within 100 ft of our aircraft. It appeared the targets were flying so fast and closing so quickly that the TCAS could not keep up with them. We stayed at altitude and on course because complying with the TCAS might have put us in a position to impact either airplane. The entire time this was happening I was talking to ATC and informing them of the situation and that we had an RA. ATC let us know that the fighters had busted MOA altitude and that they would be tracked down and action taken. We then received instructions to climb to FL360 from indy center. For paperwork purposes; we agreed with ATC to declare a 'near miss'. The entire incident from the first TCAS TA to the last TCAS instruction to climb took about one minute to transpire. The trailing fighter was so close to us that we heard the roar of its engines. The remainder of the flight was incident free.
