The troopers were dressed in what was known as the dense-atmosphere combat suit, the DAC. They were supposed to be lighter than the full vacuum kit, and technically they were, all else being equal, but since dense-atmosphere planets invariably had higher gravity than those with light or no atmospheres, the kit actually presented the men with a greater relative burden. The bulky helmets, although they still contained communicators and brainlink displays, were modified so that they didn't completely enclose the head. The dark visor was only half-face, entending to just below the eyes; the lower half of the face was covered by a transparent breathing mask. In the back, the protective shell extended to the cushioned neck ring but wasn't sealed to it. The backpack was actually larger than that of the full vacuum kit. Since, in this theater, the troopers could expect to be out in the bush for days on end without ever coming in to a service base, the pack had to incorporate air and water tanks, recyclers, spare energy pacs, minimeds, F-rations, and' even a deflated one-man bubble environment. The podlike casing of the backpack did come with a small floater in the base that offset the weight, but its bulk and inertia still made it a cumbersome piece of equipment. Most of the men had modified their kits for safety and comfort. The suits themselves had been persuaded to roll back, leaving arms and, in some cases, legs bare. Helmets were decorated with camouflage scrim, decked with fungus and foliage. Some of the troopers had hung small combat souvenirs around their necks. Taken as a whole, the effect, particularly among the longtimers, verged on the barbaric.

Although the medians steadfastly refused to say as much, the Therem troops were bogged down on this planet. They had been on JD4-1A for over two hundred days. It was supposed to have been a relatively simple operation. The Yal had a large ground garrison dug in on various parts of the planet, but they had withdrawn their large battleships and left only satellite weapon systems and smaller interplanetary craft. In the beginning, it had all gone according to the book. The cluster had moved in, and the small Yal space force had been wiped out in a matter of minutes. The larger ground installations had been pinpoint nuked, and Therem troops had gone down to mop up the survivors.

It was at this point that things started to go wrong. More than just survivors waited for the ground troops. The Yal had seeded the planet with every kind of booby trap and sleeper weapon. Large forces of specially adapted chibas had been concealed in the most difficult terrain. Packs of vicious semiintelligent miggies roamed the ice fields and the jungles, making random attacks on the Therem forces. What had looked like a routine occupation quickly turned into a slow, painful planet clearing, a war of attrition that the Therem would win in the end by sheer firepower and weight of numbers but that would cost them dearly before the last Yal surrogates were destroyed.

The suspicion began to spread through the ranks that they had been maneuvered into a trap. JD4-1A wasn't a poorly protected garrison planet but one huge sucker bet, a piece of bait that the Anah command had swallowed whole. There didn't seem to be a way out. If the cluster withdrew, the action would constitute a major retreat. The Therem couldn't allow a Yal-occupied planet to remain in a sector that was otherwise under their control. The only alternative to the bloody, protracted warfare was the total destruction of the planet, something certainly within the cluster's power to do. The only reason that the thirteen big ships didn't stand off and pound this world into a brand-new belt of asteroids was that it was against the only basic rule in this eternal conflict: A planet with natural indigenous life must not be destroyed. The rule was a legacy from the early period of the war, when planet smashing had been carried on wholesale. Both the Yal and the Therem had begun to see the eventual outcome of this behavior, and almost spontaneously and certainly without any formal communication, they both had stopped the practice. Even though, on JD4-1A, the Yal were using the rule to their advantage, the planet could not be blown to bits without a major change in policy-and it was a policy that wasn't likely to be changed. Even in this ultimately destructive war, there seemed to be a need for some limit on the destruction. In the meantime, the troopers fought and died.

The twenty had greatly changed. There were a lot of new faces. Dyrkin and Renchett were still there, seem- ingly indestructible. Helot was still hanging on. Kemlo, because of his prosthetic foot, had been retired to ship duties, but when the losses had started to build, he'd been brought back into the line. Elmo had also been brought back as overman, and he was one old-timer no one was pleased to see. Following the return from the recstar, Elmo's performance as a noncom had gone right down the tubes. The situation had deteriorated to the point where the twenty who were supposed to be under his control simply wouldn't take him seriously. Rance, out of a sense of loyalty, had covered for him as long as he could, but the time had come when it was no longer possible to hide Elmo's mistakes without endangering the men. Rance had organized a little computer trickery, and Elmo had been removed to a post in the supply center where he couldn't do any harm. As the war on JD4-1A dragged on, however, the easy, rear-echelon jobs were eliminated one by one. The fatalities among non-coms were particularly high, and according to. the records, Elmo was a perfectly able overman. He was therefore returned to his old unit to replace Overman Macin, who had been killed by chiba fire out on the plains in front of Range 27. He'd arrived only a day or so before the push up the Ten River, and as Dyrkin put it, he hadn't had time yet to foul up. None of the veterans in the twenty, though, doubted that he would.

Renchett walked over to where Hark was lying with his eyes closed. "Taking it easy there, boy?"

"Taking it while I can." Hark opened his eyes and raised his head. "Any sign of the task force?"

Renchett shook his head. "Nothing."

Hark let his head flop back. "I ain't in no hurry."

Renchett didn't say anything-he probably was in a hurry. Hark accepted that Renchett was completely unbalanced. He was part of the crew-what, for Hark, was the original crew. A man had to be true to his crew. Be- sides, Renchett was very good at killing, and the more he killed the enemy, the less enemy there was to try to kill Hark.

"What about goddamn Elmo?"

"What about him?"

"You realize we may have to do something about him?"

"I'm doing one minute at a time, and right now I'm lying down."

Renchett shrugged. "Suit yourself."

Elmo was sitting apart from the others and staring fixedly down the river. Since he'd arrived at the unit, he'd hardly communicated with the men except to give a few curt orders. He looked burned-out.

One of the replacements pointed down river. "They're coming!"

"It's the big dynes," someone said.

Hark pushed himself up on one elbow. The dynes were the biggest land fighting machines in all of the Therem Alliance. He wearily stood up. No matter how many of them he saw, he couldn't help being awed. A dyne was over a hundred meters tall, an ovoid body supported on three long spindly legs and packed with every imaginable kind of weapon. It wasn't clear whether they were composite beings or machines manned by very complex creatures. It was probably an academic point.

"Just look at those suckers!"

There were four of them wading out of the gulf and up onto dry land. Their huge feet effortlessly crushed the fleshy jungle. Hark knew that there were human troops down in that jungle, advancing behind the dynes. He was profoundly glad that he wasn't one of them. It was the worst place to be in this kind of operation. The dynes were preceded by a flight of drone ultralights, which were supposed to trigger any buried Yal weapons that might run on the command of a simple mass detector.
