A four plane formation of T-6 texan ii's was maneuvering in their assigned training area when a TCAS traffic advisory alerted flight lead to a possible bogey at their altitude and closing fast. Shortly thereafter; reporter saw another T-6 in a hard left hand turn to avoid. He was heading south at 4;500 feet MSL; and reporter's aircraft was heading north. They passed within 300 feet of each other. Had other aircraft not aggressively maneuvered; it would have flown directly through reporter's formation.

Narrative:
Near midair collision at 4;500 feet MSL. I was the division lead for a student formation flight of three. While the students were performing a series of turns; I received a TCAS traffic advisory. It extinguished after approximately 5 seconds. It was so close to us that I assumed the -2 student had inadvertently turned his transponder on and back off when the advisory extinguished. I didn't see anyone.shortly thereafter; I saw aircraft X in a hard left hand turn to avoid us. He was heading south at 4;500 feet MSL; and we were heading north. We passed within 300 feet of each other. Had he not aggressively maneuvered; he would have flown directly through our formation. I checked the tactical situation display; and we were inside of our approved working block based on training air wing five's internal de-confliction procedures. I made a radio call on our common frequency; and I received no response.
