"Full field, Quadrant Four," Buntz said, and the lower left corner of his visor showed the original 270° display. A bunker had collapsed in a cloud of dust though without a noticeable secondary explosion, and there was a new fire just north of the combat cars. The cars' tribarrels wouldn't be effective against even the tank destroyers' light armor at this range, but the enemy commander wasn't taking any chances. The Brotherhood was a good outfit, no mistake.
Eight more vehicles left the hills now that the advanced companies had spread to screen them. Pairs of mortar carriers with pairs of APCs for security followed each flanking element. The range of Brotherhood automatic mortars was about ten klicks, depending on what shell they were firing. It wouldn't be any time before they were in position around the firebase.
Rennie's combat cars were moving southward, keeping under cover. Running, if you wanted to call it that.
The Brotherhood APCs were amazingly fast, seventy kph cross-country. They couldn't fight the combat cars head-on, but they wouldn't try to. They obviously intended to surround the Slammers platoon and disgorge their infantry in three-man buzzbomb teams. Once the infantry got into position, and with the tank destroyers on overwatch to limit the cars' movement, the Brotherhood could force Lieutenant Rennie to surrender without a shot.
One of the Government howitzers fired. The guns could reach the Brotherhood vehicles in the hills, but this round landed well short. A red flash and a spurt of sooty black smoke indicated that the bursting charge was TNT.
The gunners didn't get a chance to refine their aim. A 9-cm bolt struck the gun tube squarely at the trunnions, throwing the front half a dozen meters. The white blaze of burning steel ignited hydraulic fluid in the compensator,the rubber tires, and the hair and uniforms of the crew. A moment later propellant charges stacked behind the gun went off in something between an explosion and a very fierce fire.
Two howitzers were more or less undamaged,but their crews had abandoned them. Another bunker collapsed—a third. Buntz hadn't noticed the second being hit, but a pall of dust was still settling over it. Government soldiers started to leave the remaining bunkers and huddle in the connecting trenches.
