Narrative:
Approaching gez for practice landings; I heard a helicopter in the pattern. I announced my position 10 miles northeast; 5 miles northeast; and 2 miles northeast. As I overflew the airport to turn for left downwind for runway 01; the helicopter announced he was taking off from runway 01 and staying in the pattern. I announced I was crosswind for 01. After announcing and flying downwind; I pulled power for a practice power-off 180. I announced base and final for 01. In the flare; I was suddenly yawed about 30 degrees right; banked 20 degrees right; and pitched 10 degrees up. I was able to regain control and land the airplane. As I did; I saw the helicopter sitting on the departure end of the runway. I had not seen it prior to that; which was unsurprising as his last position report put him directly behind me.despite announcing a takeoff; the helicopter evidently taxied down the runway and stopped. I announced my position on crosswind; downwind; base and final and was never acknowledged. My mistake was in never visualizing the helicopter. When on crosswind; I should have made a more concerted effort to see it and perhaps announced that I hadn't seen it. [These military helicopters] are difficult to see; by design. Otherwise; I don't see what I could have done to prevent this. For whatever reason; the [helicopter] crew did not give a new position report after announcing a departure they didn't make. Then they didn't respond to my position reports as I proceeded to get closer to them and their rotor vortices.
