Alamo Avenger: a Technology from Pandora's Star
"Huge dark metal shapes were rising out of the debris on vivid columns of violet flame. They looked like armored rectangular dinosaurs, with blunt wedge-shaped heads. Thick cannon barrels jutted out from where their eyes should have been, while smaller guns protruded from the front of the head, like lethal mandibles. Three stumpy legs were folded back against each side of their flanks as they went airborne. The air shimmered around them as force fields came on."
"The Alamo Avengers stormed over the highway at barely a hundred meters altitude. When they were a kilometer from the force field, they opened fire with their particle lances. It was as if sheet lightning was bridging the gap between them and the dome. The entire sky transformed into a blinding white maelstrom as the air disintegrated from the tremendous energy discharge."
