"Are you suited and armed? Are you ready for illumination adjustment?"
"Combatmen suited and armed." That was Sergeant Toth's voice.
"Bomb squad not ready," Dom said, and they hurried to make the last fastenings, aware that the rest were waiting for them.
"Bomb squad suited and armed."
"Lights."
As the command rang out the bulkhead lights faded out until the darkness was broken only by the dim red lights in the ceiling above. Until their eyes became adjusted it was almost impossible to see. Dom groped his way to one of the benches, found the oxygen hose with his fingers, and plugged it into the side of his helmet; this would conserve his tank oxygen during the wait. Brisk music was being played over the command circuit now as part of morale-sustaining. Here in the semidarkness, suited and armed, the waiting could soon become nerve-racking. Everything was done to alleviate the pressure. The music faded and a voice replaced it.
"This is the executive officer speaking. I'm going to try and keep you in the picture as to what is happening up here. The Edinburgers are attacking in fleet strength and, soon after they were sighted, their ambassador declared that a state of war exists. He asks that Earth surrender at once or risk the consequences. Well, you all know what the answer to that one was. The Edinburgers have invaded and conquered twelve settled planets already and incorporated them into their Greater Celtic Coprosperity Sphere. Now they're getting greedy and going for the big one. Earth itself, the planet their ancestors left a hundred generations ago. In doing this… just a moment, I have a battle report here… first contact with our scouts."
The officer stopped for a moment, then his voice picked up again.
"Fleet strength, but no larger than we expected and we will be able to handle them. But there is one difference in their tactics and the combat computer is analyzing this now. They were the ones who originated the MT invasion technique, landing a number of cargo craft on a planet, all of them loaded with matter transmitter screens. As you know, the invading forces attack through these screens direct from their planet to the one that is to be conquered. Well they've changed their technique now. This entire fleet is protecting a single ship, a Kriger class scout carrier. What this means… hold on, here is the readout from the combat computer. 'Only possibility single ship landing area increase MT screen breakthrough,' that's what it says. Which means that there is a good chance that this ship may be packing a single large MT screen, bigger than anything ever built before. If this is so — and they get the thing down to the surface — they can fly heavy bombers right through it, fire pre-aimed ICBM's, send through troop carriers, anything. If this happens the invasion will be successful."
Around him, in the red-lit darkness, Dom was aware of the other suited figures who stirred silently as they heard the words.
"If this happens." There was a ring of authority now in the executive officer's voice. "The Edinburgers have developed the only way to launch an interplanetery invasion. We have found the way to stop it. You combatmen are the answer. They have now put all their eggs in one basket — and you are going to take that basket to pieces. You can get through where attack ships or missiles could not. We're closing fast now and you will be called to combat stations soon. So — go out there and do your job. The fate of Earth rides with you."
Melodramatic words, Dom thought, yet they were true. Everything, the ships, the concentration of firepower, it all depended on them. The alert alarm cut through his thoughts and he snapped to attention.
"Disconnect oxygen. Fall out when your name is called and proceed to the firing room in the order called. Toth…"
The names were spoken quickly and the combatmen moved out. At the entrance to the firing room a suited man with a red-globed light checked the names on their chests against his roster to make sure they were in the correct order. Everything moved smoothly, easily, just like a drill. Because the endless drills had been designed to train them for just this moment. The firing room was familiar, though they had never been there before, because their trainer had been an exact duplicate of it. The combatman ahead of Dom went to port so he moved to starboard. The man preceding him was just climbing into a capsule and Dom waited while the armorer helped him down into it and adjusted the armpit supports. Then it was his turn and Dom slipped into the transparent plastic shell and settled against the seat as he seized the handgrips. The armorer pulled the supports hard up into his armpits and he nodded when they seated right. A moment later the man was gone and he was alone in the semi-darkness with the dim red glow shining on the top ring of the capsule that was just above his head. There was a sudden shudder and he gripped hard just as the capsule started forward. As it moved it tilted back ward until he was lying on his back looking up through the metal rings that banded his plastic shell. His capsule was moved sideways, jerked to a stop, then moved again. Now the gun was visible, a half-dozen capsules ahead of his, and he thought, as he always did during training, how like an ancient quick-firing cannon the gun was — a cannon that fired human beings. Every two seconds the charging mechanism seized a capsule from one of the alternate feed belts, whipped it to the rear of the gun where it instantly vanished into the breech. Then another and another. The one ahead of Dom disappeared and he braced himself — and the mechanism halted.
There was a flicker of fear that something had gone wrong with the complex gun, before he realized that all of the first combatmen had been launched and that the computer was waiting a determined period of time for them to prepare the way for the bomb squad. His squad now, the men he would lead.
Waiting was harder than moving as he looked at the black mouth of the breech. The computer would be ticking away the seconds now, while at the same time tracking the target and keeping the ship aimed to the correct trajectory. Once he was in the gun the magnetic field would seize the rings that banded his capsule and the linear accelerator of the gun would draw him up the evacuated tube that penetrated the entire length of the great ship from stern to bow. Faster and faster the magnetic fields would pull him until he left the mouth of the gun at the correct speed and on the correct trajectory to intercept…
His capsule was whipped up in a tight arc and shoved into the darkness. Even as he gripped tight on the handholds the pressure pads came up and hit him. He could not measure the time — he could not see and he could not breathe as the brutal acceleration pressed down on him. Hard, harder than anything he had ever experienced in training: he had that one thought and then he was out of the gun.
In a single instant he went from acceleration to weightlessness, and he gripped hard so he would not float away from the capsule. There was a puff of vapor from the unheard explosions, he felt them through his feet, and the metal rings were blown in half and the upper portion of the capsule shattered and hurled away. Now he was alone, weightless, holding to the grips that were fastened to the rocket unit beneath his feet. He looked about for the space battle that he knew was in progress, and felt a slight disappointment that there was so little to see.
Something burned far off to his right and there was a wavering in the brilliant points of the stars as some dark object occulted them and passed on. This was a battle of computers and instruments at great distances. There was very little for the unaided eye to see. The spaceships were black and swift and — for the most part — thousands of miles away. They were firing homing rockets and proximity shells, also just as swift and invisible. He knew that space around. him was filled with signal jammers and false signal generators, but none of this was visible. Even the target vessel toward which he was rushing was invisible. For all that his limited senses could tell he was alone in space, motionless, forgotten.
