Narrative:

Departed tus runway 29R with assigned heading of 300 degrees after takeoff. Departure control subsequently turned us to 310 degrees, followed approximately 1 min later with a turn to 070 degrees to join the departure. 1/2 way through the turn, we received a TA, followed quickly by an RA to descend, at about the same time the controller was advising us of the traffic. The captain (PF) disengaged the autoplt, reversed the climb to a descent and descended approximately 500 ft. An A10, probably departing out of davis monthan AFB, passed approximately 1/2 mi off our right wing and 1000 ft above us. After the clear of traffic call, we reinitiated our climb and resumed the departure. This was a potentially disastrous situation which, I believe, was caused by lack of coordination on the ground and the fact the A10 was on a UHF frequency and the airliner on VHF. I am sure the tus departure controller would not have knowingly vectored us into a military fighter, so I would advise looking closely at the procedures in place for the collation of military and civilian traffic, along with the existing safeguards for separation. I don't believe the A10 ever saw us and we initiated the evasive action from the TCASII RA, before visual contact with the A10.

Title: A DEP CRJ HAS A POTENTIAL CONFLICT WITH A DEP A10 MIL ACFT WHILE ON DEP FREQ WITH CTLR AT TUS, AZ.

Narrative: DEPARTED TUS RWY 29R WITH ASSIGNED HDG OF 300 DEGS AFTER TKOF. DEP CTL SUBSEQUENTLY TURNED US TO 310 DEGS, FOLLOWED APPROX 1 MIN LATER WITH A TURN TO 070 DEGS TO JOIN THE DEP. 1/2 WAY THROUGH THE TURN, WE RECEIVED A TA, FOLLOWED QUICKLY BY AN RA TO DSND, AT ABOUT THE SAME TIME THE CTLR WAS ADVISING US OF THE TFC. THE CAPT (PF) DISENGAGED THE AUTOPLT, REVERSED THE CLB TO A DSCNT AND DSNDED APPROX 500 FT. AN A10, PROBABLY DEPARTING OUT OF DAVIS MONTHAN AFB, PASSED APPROX 1/2 MI OFF OUR R WING AND 1000 FT ABOVE US. AFTER THE CLR OF TFC CALL, WE REINITIATED OUR CLB AND RESUMED THE DEP. THIS WAS A POTENTIALLY DISASTROUS SIT WHICH, I BELIEVE, WAS CAUSED BY LACK OF COORD ON THE GND AND THE FACT THE A10 WAS ON A UHF FREQ AND THE AIRLINER ON VHF. I AM SURE THE TUS DEP CTLR WOULD NOT HAVE KNOWINGLY VECTORED US INTO A MIL FIGHTER, SO I WOULD ADVISE LOOKING CLOSELY AT THE PROCS IN PLACE FOR THE COLLATION OF MIL AND CIVILIAN TFC, ALONG WITH THE EXISTING SAFEGUARDS FOR SEPARATION. I DON'T BELIEVE THE A10 EVER SAW US AND WE INITIATED THE EVASIVE ACTION FROM THE TCASII RA, BEFORE VISUAL CONTACT WITH THE A10.
