After a leisure flight of 1.4 hours in the 15 mi radius of anb airport during which I monitored anniston FSS on 123.6 and reported my position as other aircraft made contact. I had been doing steep turns and slow flight 6 NM east of anb for about 30 mins. I headed toward the anb airport and contacted FSS, informed them that I was 3 mi east out of 1800 ft with 3 rotorcraft in sight to the north. I shortly notified anb FSS that I was entering a right downwind (which is published for and due to mountains north of field) and that I still had 3 rotorcraft in sight north of the airport. I turned right base for runway 5 and called my position to FSS and traffic. I had watched the 3 rotorcraft pass to the left of my heading (on base leg) and was calling FSS to report turning final for runway 5 when the flight of 3 rotorcraft cut directly in front of me. They were in a steep, descending turn for runway 5. I called abort on the radio as I made an abrupt hard climbing left turn, then the flight of 3 helicopters called FSS (anb) and announced 'flight of 3 on final for runway 5.' I was close enough to read 'united states of america' on the side of one. Anyway, I circled and let them land. I asked if they could call clear of the runway. They did, and I landed and secured my aircraft. Once I was able to get past the armed militia men, I asked for the PIC, one of the 20 or so men said 'that's me.' I gave him a piece of my mind. He said he had 'radio trouble' and did not know why he had flown a l-hand pattern. These guys did not have any government markings, just olive drab clothes and little plastic tags turned backwards, clipped to their vest pocket. The helicopters just had united states of america on the side, pine green (not olive drab) with white tops and small lettering near the tail. This event (incident) would have easily been prevented if these guys had communicated their intentions.

Title: SMA PLT IN TFC PATTERN SIGHTS FLT OF 3 HELIS TO THE N. HE MAKES CORRECT R-HAND PATTERN AND HAD NMAC WITH THE 3 HELIS ON TURN FROM BASE TO FINAL. THE HELIS SAID THEY HAD COM PROBS.
Narrative: AFTER A LEISURE FLT OF 1.4 HRS IN THE 15 MI RADIUS OF ANB ARPT DURING WHICH I MONITORED ANNISTON FSS ON 123.6 AND RPTED MY POS AS OTHER ACFT MADE CONTACT. I HAD BEEN DOING STEEP TURNS AND SLOW FLT 6 NM E OF ANB FOR ABOUT 30 MINS. I HEADED TOWARD THE ANB ARPT AND CONTACTED FSS, INFORMED THEM THAT I WAS 3 MI E OUT OF 1800 FT WITH 3 ROTORCRAFT IN SIGHT TO THE N. I SHORTLY NOTIFIED ANB FSS THAT I WAS ENTERING A R DOWNWIND (WHICH IS PUBLISHED FOR AND DUE TO MOUNTAINS N OF FIELD) AND THAT I STILL HAD 3 ROTORCRAFT IN SIGHT N OF THE ARPT. I TURNED R BASE FOR RWY 5 AND CALLED MY POS TO FSS AND TFC. I HAD WATCHED THE 3 ROTORCRAFT PASS TO THE L OF MY HDG (ON BASE LEG) AND WAS CALLING FSS TO RPT TURNING FINAL FOR RWY 5 WHEN THE FLT OF 3 ROTORCRAFT CUT DIRECTLY IN FRONT OF ME. THEY WERE IN A STEEP, DSNDING TURN FOR RWY 5. I CALLED ABORT ON THE RADIO AS I MADE AN ABRUPT HARD CLBING L TURN, THEN THE FLT OF 3 HELIS CALLED FSS (ANB) AND ANNOUNCED 'FLT OF 3 ON FINAL FOR RWY 5.' I WAS CLOSE ENOUGH TO READ 'UNITED STATES OF AMERICA' ON THE SIDE OF ONE. ANYWAY, I CIRCLED AND LET THEM LAND. I ASKED IF THEY COULD CALL CLR OF THE RWY. THEY DID, AND I LANDED AND SECURED MY ACFT. ONCE I WAS ABLE TO GET PAST THE ARMED MILITIA MEN, I ASKED FOR THE PIC, ONE OF THE 20 OR SO MEN SAID 'THAT'S ME.' I GAVE HIM A PIECE OF MY MIND. HE SAID HE HAD 'RADIO TROUBLE' AND DID NOT KNOW WHY HE HAD FLOWN A L-HAND PATTERN. THESE GUYS DID NOT HAVE ANY GOV MARKINGS, JUST OLIVE DRAB CLOTHES AND LITTLE PLASTIC TAGS TURNED BACKWARDS, CLIPPED TO THEIR VEST POCKET. THE HELIS JUST HAD UNITED STATES OF AMERICA ON THE SIDE, PINE GREEN (NOT OLIVE DRAB) WITH WHITE TOPS AND SMALL LETTERING NEAR THE TAIL. THIS EVENT (INCIDENT) WOULD HAVE EASILY BEEN PREVENTED IF THESE GUYS HAD COMMUNICATED THEIR INTENTIONS.
