Narrative:

Military aircraft (in this case 2 A10's) climbing out of the cannon MOA on their way to the truman MOA often conflict with our traffic (as was the case with a twin cessna on this occasion) rarely are they talking to air traffic. This twin cessna had to descend rapidly to avoid the traffic. I feel that the military aircraft should be required to talk to ATC at all times. Twin cessna on GPS final to runway 18 at 4000 ft. I noticed popup primary target just southeast of him. By the time the traffic call was halfway out of my mouth the primary became a 1200 code and showed an altitude of 4000 ft. I changed the TA to a traffic alert mid-transmission and advised the twin to descend immediately. He did and reported the traffic as 2 rapidly climbing A10's. I had this exact situation a few months ago between a crj and 2 A10's. That time the A10's weren't even squawking a code. The cannon and truman MOA's are only about 25 mi apart. Aircraft transitioning from one to the other should be in radio contact with ATC as this is also an arrival corridor for sgf.

Title: SGF CTLR DESCRIBED CONFLICT BTWN TFC ON APCH TO LBO AND MIL TFC FROM THE CANNON MOA TO TRUMAN MOA.

Narrative: MIL ACFT (IN THIS CASE 2 A10'S) CLBING OUT OF THE CANNON MOA ON THEIR WAY TO THE TRUMAN MOA OFTEN CONFLICT WITH OUR TFC (AS WAS THE CASE WITH A TWIN CESSNA ON THIS OCCASION) RARELY ARE THEY TALKING TO AIR TFC. THIS TWIN CESSNA HAD TO DSND RAPIDLY TO AVOID THE TFC. I FEEL THAT THE MIL ACFT SHOULD BE REQUIRED TO TALK TO ATC AT ALL TIMES. TWIN CESSNA ON GPS FINAL TO RWY 18 AT 4000 FT. I NOTICED POPUP PRIMARY TARGET JUST SE OF HIM. BY THE TIME THE TFC CALL WAS HALFWAY OUT OF MY MOUTH THE PRIMARY BECAME A 1200 CODE AND SHOWED AN ALT OF 4000 FT. I CHANGED THE TA TO A TFC ALERT MID-XMISSION AND ADVISED THE TWIN TO DSND IMMEDIATELY. HE DID AND RPTED THE TFC AS 2 RAPIDLY CLBING A10'S. I HAD THIS EXACT SITUATION A FEW MONTHS AGO BTWN A CRJ AND 2 A10'S. THAT TIME THE A10'S WEREN'T EVEN SQUAWKING A CODE. THE CANNON AND TRUMAN MOA'S ARE ONLY ABOUT 25 MI APART. ACFT TRANSITIONING FROM ONE TO THE OTHER SHOULD BE IN RADIO CONTACT WITH ATC AS THIS IS ALSO AN ARR CORRIDOR FOR SGF.
