"Get the Lieutenant out of here," the Master Chief barked. He raised his knee to his chest and lashed out with a straight kick. His boot connected with the Elite's breastplate. The alien's energy shield flared, then faded, and its breastplate cracked like porcelain beneath the force of the blow.

It had been a long day. Djbril had started before dawn with a detailed briefing on the new gun system, how the VADS held and distinguished a dozen clips with whatever mix of ammunition she chose. He showed her how to open the “turtle shell” to replace the magazines in their racks that led to the crab-arm “feeders” and the control unit, a tiny pocket PC built into the buckle-cover at the front of the harness. Wireless technology linked the microphone headset to the control unit. He had created VADS almost from scratch, with a little assistance from some college engineering students and a twelve-thousand-pound check from Lady Croft.
The bullets themselves came in six flavors: armor-piercing for hard targets, fléchette for soft targets you wished to turn into sausage stuffing, pure explosive, incendiary, illumination, and less-lethal rubber bullets. For maximum destruction, he recommended a mix of armor-piercing, explosive, and incendiary. “A killer cocktail,” he’d said that morning, demonstrating it on a mannequin in body armor placed within an upright freezer.
