Narrative:
IFR to lax. On descent, socal approach said 'cross palmdale at or below 10000 ft, cross boget at 8000 ft' (boget is 12 NM beyond pmd on the kimmo arrival.) we were on the airway inbound to pmd from hec. Socal then gave us a vector direct boget. We were just established on a heading of about 250 degrees to boget when TCASII called 'traffic.' we saw a california division of forestry P2V air attack bomber at our 2 O'clock position (right out of the sun). ATC called a 'traffic alert' as I kicked off the autoplt and began to level off. I could see we would miss him. The P2V was in a slow descent, going straight ahead and passed about 600 ft directly under us. The nearest fire was about 30 mi on our left. I don't think the P2V ever saw us as it continued on its way. We continued our descent and landed at lax uneventfully. The TCASII saved our bacon. ATC was somewhat slow to call the traffic. The sun (and the ATC vector) were also contributing factors. I need to look outside more on arrs.

Title: E120 FLC INITIATES A TCASII MANEUVER JUST AHEAD OF A SOCAL TFC ALERT FOR A DEPT OF FORESTRY P2V APCHING A FIRE S OF PMD VORTAC.
Narrative: IFR TO LAX. ON DSCNT, SOCAL APCH SAID 'CROSS PALMDALE AT OR BELOW 10000 FT, CROSS BOGET AT 8000 FT' (BOGET IS 12 NM BEYOND PMD ON THE KIMMO ARR.) WE WERE ON THE AIRWAY INBOUND TO PMD FROM HEC. SOCAL THEN GAVE US A VECTOR DIRECT BOGET. WE WERE JUST ESTABLISHED ON A HDG OF ABOUT 250 DEGS TO BOGET WHEN TCASII CALLED 'TFC.' WE SAW A CALIFORNIA DIVISION OF FORESTRY P2V AIR ATTACK BOMBER AT OUR 2 O'CLOCK POS (RIGHT OUT OF THE SUN). ATC CALLED A 'TFC ALERT' AS I KICKED OFF THE AUTOPLT AND BEGAN TO LEVEL OFF. I COULD SEE WE WOULD MISS HIM. THE P2V WAS IN A SLOW DSCNT, GOING STRAIGHT AHEAD AND PASSED ABOUT 600 FT DIRECTLY UNDER US. THE NEAREST FIRE WAS ABOUT 30 MI ON OUR L. I DON'T THINK THE P2V EVER SAW US AS IT CONTINUED ON ITS WAY. WE CONTINUED OUR DSCNT AND LANDED AT LAX UNEVENTFULLY. THE TCASII SAVED OUR BACON. ATC WAS SOMEWHAT SLOW TO CALL THE TFC. THE SUN (AND THE ATC VECTOR) WERE ALSO CONTRIBUTING FACTORS. I NEED TO LOOK OUTSIDE MORE ON ARRS.
