Simultaneously with Central's laconic warning, giants tore a strip off the sky. The rebel shells dropped but their bursts were smothered in the roar of the Regiment's own rocket howitzers boosting charges to titanic velocity for the several seconds before their motors burned out. Ten meters from the muzzles the rockets went supersonic, punctuating the ripping sound with thunderous slaps. Danny swung his hose toward the grove of trees, the only landmark visible on the hilltop. His burst laced it cyan. Water, flash-heated within the boles by the gunfire, blew the dense wood apart in blasts of steam and splinters. A dozen other guns joined Pritchard's, clawing at rock, air, and the remaining scraps of vegetation.
"Dead on," Central snapped to the artillery. "Now give it batteryfive and we'll show those freaks how they should've done it."
Kowie hadn't buttoned up. His head stuck up from the driver's hatch, trusting his eyes rather than the vision blocks built into his compartment. The tanks themselves were creations of the highest technical competence, built on Terra itself; but the crews were generally from frontier worlds, claustrophobic in an armored coffin no matter how good its electronic receptors were. Danny knew the feeling. His hatch, too, was open, and his hand gripped the rounded metal of the powergun itself rather than the selsyn unit inside. They were climbing sharply now, the back end hopping and skittering as the driver fed more juice to the rear fans in trying to level the vehicle. The bow skirts grounded briefly, the blades spitting out a section of hillside as pebbles.
For nearly a minute the sky slammed and raved. Slender, clipped-off vapor trails of counter-battery fire streamed from the defiladed artillery. Half a minute after they ceased fire, the drumbeat of shells bursting on the rebels continued. No further incoming rounds fell.
Two Star lurched over the rim of the hill. Seconds later the lead blowers of K and M bucked in turn onto the flatter area. Smoke and ash from the gun-lit brushfire shoomped out in their downdrafts. There was no sign of the enemy, either Densonite rebels or Fosters crew—though if the mercenaries were involved, they would be bunkered beyond probable notice until they popped the cork themselves. "Tank Section, ground! Ground in place and prepare for director control."
Danny hunched, bracing his palms against the hatch coaming. Inside the turret the movement and firing controls of the main gun glowed red, indicating that they had been locked out of Pritchard's command. Kowie lifted the bow to kill the tank's immense inertia. There was always something spooky about feeling the turret purr beneath you, watching the big gun snuffle the air with deadly precision on its own. Danny gripped his tribarrel, scanning the horizon nervously. It was worst when you didn't know what Central had on its mind . . . and you did know that the primary fire control computer was on the fritz—they always picked the damnedest times!
"Six aircraft approaching from two-eight-three degrees," Central mumbled. "Distance seven point ought four kays, closing at one one ought ought."
Pritchard risked a quick look away from where the gun pointed toward a ridgeline northwest of them, an undistinguished swelling half-obscured by the heat-wavering pall of smoke. Thirteen other tanks had crested the hill before Central froze them, all aiming in the same direction. Danny dropped below his hatch rim, counting seconds.
The sky roared cyan. The tank's vision blocks blanked momentarily, but the dazzle reflected through the open hatch was enough to make Pritchard's skin tingle. The smoke waved and rippled about the superheated tracks of gunfire. The horizon to the northwest was an expanding orange dome that silently dominated the sky.
"Resume advance." Then, "Spectroanalysis indicates five hostiles were loaded with chemical explosives, one was carrying fissionables."
Danny was trembling worse than before the botched attack. The briefing cubes had said the Densonites were religious nuts, sure. But to use unsupported artillery against a force whose satellite spotters would finger the guns before the first salvo landed; aircraft—probably converted cargo haulers—thrown against director-controlled powerguns that shot light swift and line straight; and then nukes, against a regiment more likely to advance stark naked than without a nuclear damper up! They weren't just nuts—Thrush central government was that, unwilling to have any of its own people join the fighting—they were as crazy as if they thought they could breathe vacuum and live. You didn't play that sort of game with the Regiment.
