The Placidan troops were in a rough circle of a dozen bunkers connected by trenches. In the center of the encampment were four 15-cm conventional howitzers aiming toward the Spine from sandbagged revetments. The trenches were shallow and didn't have overhead cover; ammunition trucks were parked beside the guns without even the slight protection of a layer of sandbags.
According to the briefing materials,the firebase also had two calliopes whose task was to destroy incoming shells and missiles. Those the Placidan government bought had eight barrels each, arranged in superimposed rows of four.
Buntz couldn't see the weapons on his display. That meant they'd been dug in to be safe from direct fire, the only decision the Placidan commander'd made that he approved of. Two calliopes weren't nearly enough to protect a battalion against the kind of firepower a Brotherhood commando had available, though.
The combat cars of 3d Platoon, G Company, were laagered half a klick south of the Government firebase. The plains had enough contour that the units were out of direct sight of one another. That wouldn't necessarily prevent Placidans from pointing their slugthrowers up in the air and raining projectiles down on the Slammers, but at least it kept them from deliberately shooting at their mercenary allies.
Buntz' pickup careted movement on the foothills of the Spine to the north. "Helmet," he said, enabling the voice-activated controls. "Center three-five-oh degrees, up sixteen."
The magnified image showed the snouts of three air-cushion vehicles easing to the edge of the evergreen shrubs on the ridge nearly twenty kilometers north of the Government firebase. One was a large armored personnel carrier; it could carry fifteen fully armed troops plus its driver and a gunner in the cupola forward. The APC's tribarrel was identical to the weapons on the Slammers' combat cars, a Gatling gun which fired jets of copper plasma at a rate of 500 rounds per minute.
The other two vehicles were tank destroyers. They used the same chassis as the APC, but each carried a single 9-cm high intensity powergun in a fixed axial mount—the only way so light a vehicle could handle the big gun's recoil.At moderate range—up to five klicks or so—a 9-cm bolt could penetrate
