Koban 4: Shattered Worlds (5 page)

Thad knew the bulk of the Kobani reinforcements could not arrive from on top of the dome before the Krall got some of their warriors out of the stairwells. Then grenades would risk friend and foe alike. That happened sooner than expected.

Suddenly, the Krall sprang the next part of the ambush, apparently only waiting for the smoke to spread adequately. Even the concept of an ambush proved that the Krall were learning tactics from humans. They had rarely planned such actions in the past, and this one was obviously well thought out, at least for them.

The elevator doors suddenly rose nearly simultaneously, probably on some prearranged cue, because the Krall didn’t have com set use. Of course, their visors could show them a time hack they could all use, and pass via word of mouth. The armored warriors that swarmed out had infiltrated up through holes cut in the elevator floors. The Krall in front were carrying something that explained their continued resistance in the stairwells, despite hundreds of grenades lobbed down the stairwells. The warriors in the front ranks held floor to head height metal shields. The depleted uranium pellets couldn’t penetrate those, even if some did make it under the bottoms or through the gaps. They obviously had learned from reports of the previous raids, and expected the raiders to head for the factory entrances.

This battle was turning into a melee of close infighting, just the type the Krall liked. The Kobani were more than a match physically for any individual Krall, but this could devolve into a disorganized struggle, with no way of knowing how many of the enemy they faced. Thad had started with only six hundred and eight Kobani, because they had assumed this dome would be as relatively unguarded as the others had been on the previous raids. Big miscalculation.

With direct targets to fire at, the Kobani were taking out some of the Krall behind the shield wall as they strove to peek over the top, or when they fired at wispy areas in the smoke, seeking the nearly invisible enemy. More canisters of the smoke generators flew over the shields towards where human laser or plasma bolts originated. Without being told, many of the Kobani switched to the microwave beams, which generated heat at their focal point, but did not leave as clear a trail through the air back to the origin. Following their training, they were constantly moving, firing and changing position. Because they were on three sides of the hall, they had shots at the backs of some of the warriors rushing out of the elevators when they pushed too far into the open.

Shooting a shield holder in the back of his helmet with his microwave heat beam, Ethan was gratified to see four other warriors suddenly drop their shields to rip at smoldering hot helmets, when other troopers worked to eliminate that particular advantage. Thad, seeing it happen, made a broadcast.

“Target shield holders. Then toss any grenades you have left through the gap.”

The level of thunderous explosions suddenly increased for a short time, and rattling pellets filled the air with ricochets off armor, walls and floors, accompanied by many wet sounding splats and roars of pain. This was of some risk to the spec ops, and several were wounded when pellets penetrated their suits before losing momentum, via rebounding from an intermediary surface. The majority of the grenades were dropped into clusters of warriors, piling them up in a matter of seconds, but that depleted the supply and the explosions soon diminished. That was the cue for the forces farther down the stairs to rally and charge up, without the concern of running over a just tossed grenade lying on the steps, detonating behind the shield wall.

Thad could see that the number fifteen appeared by a red icon, indicating there had been that many serious injuries or deaths among his eighty-four sappers. Now the warriors that had been held below the first landing of the stairs by the grenades were leaping up them, flying out of the openings, as they went high to seek their enemy in what had literally become the fog of war.

With the turbulence in the room so high, their carefully thought out detection method for their invisible prey was more limited than if they had been lying in wait, with the gas already deployed, floating and still, evenly distributed across the room and into the corridors. Movements through that would have been far more noticeable. The Krall would make an adjustment for the next time they used this tactic, but Thad’s concern was how his force could survive this time.

There were already several hundred Krall in the large hall, and the volume of rifle fire was pushing the humans back towards the radial corridors that led away from the dome’s center. If that happened, the troopers along the back of that press would not see as many targets to shoot. The human rate of fire into the swarm of Krall, who were perfectly willing to absorb injuries and losses, could wear down those at the front of the massed human troops. Thad could see friendly green icons moving closer from behind them, to bring up support from the rear. However, they couldn’t fire on the Krall with their own people in the way, especially not if Thad’s force was forced down the long hallways towards them. That sort of numbers game of attrition suited the enemy, and was not what the raiders wanted to accept.

Thad was on the verge of ordering a rapid pull back from the lower level of the dome when he was amazed by a sudden blossoming of green icons on his visor. They were in a ring around the central hall, on the level above them. He had set his visor to exclude friendly icons that were much above the ground floor location, to prevent his confusing them with his own smaller force. Now the troopers searching the upper structure had started dropping or climbing down through the broken levels and had reached the three-story ring of balconies that circled the central halls in all Krall domes.

Much of the shooting from the Krall had grown more concentrated as the sapper force had retreated towards the only points of retreat and cover they had. Now suddenly, Krall fire was directed elsewhere. Upwards.

The spec ops on the rings of balconies, particularly those on the top two levels (above Thad’s arbitrary vertical cutoff of icon positions), were higher than the layer of smoke that revealed movement through its translucent wisps. They were having an old-fashioned turkey shoot at the heads of completely exposed Krall.

Thad wanted to visit Earth someday, to learn where that ancient term originated. What in hell was a turkey that it was so stupid as to be killed so easily? However, he was pleased with the results here, wherever the term originated.

With no possible cover from incredibly accurate and rapid firing from all sides and from above, the Krall had to retreat from the withering fire. Initially, never having had to retreat from a human attack previously, those trying to fight their way up out of the stairwells or climb up through the floor openings inside the elevators, resisted being pushed back by the withdrawing warriors.

Thad, who had a good command of low Krall, and some measure of understanding of high Krall, wasn’t aware of a word for “retreat” or “withdraw” in either language, any more than they had one for “friend.”

In several more minutes, the enemy had been forced back into the stairwells, where the first landings turned a corner, and gave them cover. Per his suit AI, Thad saw that there were over five hundred dead or dying warriors in the hall and elevators. There were an unknown number down in the stairwells. Shooting and killing wounded Krall as they approached, Sarge, with Carson beside him, stayed clear of the stairwells. Obviously, he wanted to know how they would proceed next.

Troopers designated for administering first aid were moving to the red and yellow icons indicated on their visors, to assess which ones needed evacuation for treatment at med labs in four of the shuttles. The suit systems proved depressingly accurate for the red icons. All but one of the eighteen indicated now were already dead, and that lone surviving woman would never make it to a med lab.

As Sarge, his second in command of the factory assault group joined him, Thad Linked to Dillon who was their air cover, and included his eight sapper team leaders. Those eight included Ethan and Carson, although he was shocked to discover that Yilini Jastrov was dead, and that Jorl Breaker now led that team. Yil had just “signed the line” with the much older (and now young looking) Clarice Femfreid last month. They had signed for one contracted child, and because Clarice had not made this mission, it was quite possible she had not cleared medical due to conception. Damn!

Shaking the loss off, knowing Yil was a close friend of Ethan and Carson, he didn’t look at them as the visors automatically registered Jorl as the replacement team leader. “We can’t take the time or accept the casualties needed to fight our way down those stairs, not knowing how many warriors we might face. We clearly caught them by surprise when we arrived, but just as clearly they had a reception planned below if we did, based on our previous courses of action. They know we take out the dome observers, blast any ships on the tarmac, and enter the factory to blow up the equipment and flood the works.

“I don’t think we can afford the time to clear them out and fight our way down. I’m open to alternative ideas. Sarge, you first.”

“We know the Prada have work entrances at their villages, or close by. We might try descending there.”

“The Krall know those are there too, and we can’t spend time fighting our way between levels even if those entrances could get us in unopposed. This time we know there are Krall down there in force.” He turned his head to look as new explosions from grenades blew dust up the stairs, and there was almost continuous if ineffectual Krall shooting around the stairwell corners of the landings.

He had a question. “Dillon, were there many Prada coming out of the dome after the fighting started? Four that Sarge directed to leave were killed by the Krall right at the start of shooting.”

“I saw perhaps a hundred run across the half mile of open ground from the dome to reach the southern edge of the trees. I saw hundreds more of them in the woods, and their IR signatures vanished deeper into the trees. I also saw a continuous stream of them pass from the northeast edge of the woods towards the west. I’m guessing they were coming out of the factory. They would have heard the explosions, and their merciful Rulers never care if they are caught in the crossfire. I believe they may have evacuated on their own.”

“OK. I think we have to take the chance that they were perceptive enough to get away from the fighting when they heard it start; The Krall fought each other for thousands of years, so this can’t be an entirely new experience in their long history as their slave workers.

“Let me hear ideas of how to flood and blow up this factory complex if we can’t go down inside and do it personally and thoroughly.” There was only a brief moment of silence, when the expected two most adventuresome and daring individuals both spoke at once.

“OK. I can’t listen to both of you at once, and to avoid favoritism, which will rear its head anyway, I’ll let Carson go first, then Ethan.”

With a thumb up to Ethan, Carson made his suggestion. One he’d been considering ever since the Krall proved today they were better prepared to defend their factory.

“We need to flood the factory to ruin much of the equipment, and delay their restarting and repairing it after we pull out. We might be able to do that without blowing up the cooling water pipes from inside the factory. They pull cold glacier water in from that large lake a mile to the east, and pump the warmer water out into the river on the southwest side. There have to be large intakes in the lake. We may be able to float explosives into them to go down into the factory to the pumps, and explode when well below ground level. Water will then pour in by gravity, as it did at other sites.”

Thad nodded. “OK. But they must have grill covers over the intakes, and we know they use pumps to move the water in faster than gravity can flow the water, and then is pumped back out. The outgoing pumps might prevent full flooding if they stay operational.”

Carson had a reply prepared. “We can remove any grills, either by burning them off where they attach, or with smaller explosives. Our suits are as good underwater as they are in space or a hazardous atmosphere. It’s my idea; I’ll go in the water.” No surprise there.

Ethan, who had had a different idea, suddenly saw a way the two could work together. “His idea will work better if we also do what I was thinking. The factory doesn’t have to be entered through any of the prepared openings that the Krall are defending. Much of this entire area is overlying the factory, and we have the typical factory layout on our visor maps for navigation. The mapping will still work topside. If we blast holes through the factory ceiling from up here, at places where there is a considerable drop below those points, we can toss in our explosives.

“Many of them were going to be set to explode when water depth and pressure was high enough for hydrostatic shock to do more damage anyway. I’d suggest we drop one package down along the outlet pipes where they rise, to fall near the pumps that push water back up to the river. Carson lets the water in, I stop it from being pumped out, and our other explosives go off when the water is deep enough.”

Thad liked what he was hearing. “It’s slower, but that might work. We don’t have to wait for all the Prada to get out and any that are still down there can climb faster than the water will rise. I don’t think we can wait for the water to fill the whole cavity anyway, since that could take more than a day. Carson, take your team with you in a shuttle, and two of the Q-rupters to cut open any grills so you don’t have to blast. Ethan, the factory roof is no more than a hundred feet below ground in most places. We can use more of those drilling tools to help weaken the rock and soil overhead to blast through easier and quickly. Toss in the explosives before the Krall even arrive to see what we did. They’ll think we’re coming in through those holes. We can blow a few holes in other places, just to keep them guessing and moving in the wrong directions. Let’s get started, while our boys are holding them in their holes here.”
