soon were reminded our home wasn’t in the best condition. It was demolished, smashed to sticks by a strike on a nearby building.
“Hmm,” I said, realizing I wasn’t going to get laid in this place anytime soon.
Sandra gave a deep sigh, but she didn’t start crying. I think before our campaign against the Worms and the long journey home fighting against the Macros, she would have broken down. Now, she understood that things were just things. As long as the people you cared about were alive, crying wasn’t worthwhile.
“I’ve got an idea,” she said, then led me down to the sea.
It was getting dark now, but when we took off our battle suits and slipped into the waves, they were very warm. I looked off down the beach and saw a lot of dead sea creatures on the sand. All the hits in the water had killed thousands of fish. I turned her away from the washed up bodies.
“Why here?” I asked.
“Because those damned turrets can’t see us now,” she said. “I want to have some fun before you fix them all and they stare at me again.”
I laughed, and as the darkness fell we enjoyed ourselves in the waves. The water still felt warmer than usual, almost hot, but I’d checked my Geiger counter before we went out there. It registered increased activity with a mild amount of clicking. It was nothing a couple of Star Force marines couldn’t handle.

About thirty-six hours later, a fresh dawn broke over Andros. The radioactive clouds had dissipated, brought to Earth by a light drizzling rain. I stood in my battle suit alongside a good five thousand of my comrades. We were organized in tight units, because radio transmissions were going to be our biggest problem. I’d spent the last day and a half coming up with solutions.
The normal means of communications underwater consisted of either sonic signals-essentially shouting at one another with directed vibrations, or very low frequency radio. Of the two, VLF radio was much less workable. Conductive seawater was not a good medium for radio transmissions of any kind, but with long wavelengths and huge antennas it could be managed over distances of several hundred yards. Unfortunately, using low frequencies meant really long antennas-much longer than a man was tall.
We had the opposite problem with sound. It traveled too far and worked too well. A good loud noise under the ocean, such as a dolphin’s clicking, carried quite a distance. Whale songs went the furthest, in some cases thousands of miles. I didn’t know how sensitive the Macros were to underwater sounds, but I figured our clanking along in armor was going to be noisy enough.
In the end, we decided on a hybrid strategy. We would use sound only for longer range communications. After all, it worked pretty well for the whales. We used radio for close, whispered conversations between soldiers in the same unit.
I built a brainbox attached to a directional hydrophone it could manipulate and had a non-com in every unit carry one. It wasn’t perfect, but it worked. The biggest problem with this sort of communication was the lack of security. If the Macros were listening, they would hear our command chatter. Accordingly, I ordered each team to maintain sonic silence until the battle began, barring some kind of disaster.
Every company had to operate independently under this model, due to isolation. We had suit radio, but that didn’t work very well under the waves. A man’s normal shouting voice on the beach had more range than our radios did at the bottom of the ocean. Separating into companies of one hundred marines, we each had a geographic location we were to get down to. We weren’t sure where the enemy was in the trench, but we were going to have to find them on foot. It was a shotgun approach, but I didn’t know what else to do. We’d tried getting aerial photos and using sonar, but hadn’t seen much down there. Anyone who has searched deep water for a shipwreck can tell you it’s easier to find a rock on the Moon than find an object at the bottom of the sea. Essentially, you had to go down there and look around.
“Kwon,” I said, clanking out onto the beach, “let’s move our team out.”
“Moving out, sir!”
We weren’t the first ones to enter the sea. I’d already sent twenty companies forward. I had them fly out over the waves first so they could move faster, but when the water got deep-which it did with alarming suddenness a about a mile offshore-they were to drop down directly, hugging the cliff and letting gravity do the trick. They sank like stones, or maybe like big steel bricks.
Soon, it was our turn to move out. We engaged our repellers and left the sandy beach behind. We leaned our bodies forward and increased our speed. The repellers pushed us forward and away from the water at the same time. Like a hundred strange little helicopters, we flew over the cresting whitecaps. As we sailed over the waves at around a hundred knots. Every marine left a white line of froth in the water due to the pushing of his repellers in the bright, Caribbean-blue surface.
“Is it okay to use radio while flying, sir?” Kwon asked me.
“Yes, as long as we don’t overdo it and keep the power low on our transmissions. As I said in the briefing, the signals won’t get down to the Macros through the seawater.”
Kwon pointed overhead. “What about them?”
“The enemy fleet has withdrawn to higher orbit, I’m happy to report. They apparently don’t want to sit close to the Earth’s surface.”
“Why have they pulled back?”
“Maybe they think we could nuke them in a surprise sucker-punch. I wish we had a hundred subs waiting to do just that, but we don’t.”
Kwon stopped asking questions. It was just as well, because we’d reached the end of the line. It was easy to see where the land-shelf ended from an aerial view. This close to it, I found it harder to tell. The water did look somewhat deeper blue. Below us was a cliff thousands of feet deep. I leaned back and halted my forward motion.
“Slow down, this is it,” Kwon shouted, seeing my move.
The company clustered around, tipping their helmets awkwardly to look down in the water. “Let’s drop,” I said, and I switched off my repellers.
The water splashed around me and I sank with dramatic speed. Being accustomed to being much more buoyant, it was alarming to go down so fast. I felt like I was drowning. I watched as dark cliffs covered in crusty growths whirled past my faceplate. I looked up and saw a spiral of bubbles spinning away overhead toward the silvery surface. Below, the water was deep blue. As I continued to drop, the water above grew darker and the surface was no longer discernable. Below, the sea had turned an oily black.
I snapped on my suit lights. A dozen others did the same all around me. Their existence was a comfort.
Normally, a dive like this took many stages and an ever increasing level of pressure inside the suit which had to be built up carefully to avoid popping eardrums and other unpleasant things. Fortunately, I had a team of about a zillion nanites working internally to balance out my body. On the way back up however, I knew we would have to take it slower to avoid decompression sickness, nanites or no.
My suit hissed and creaked as the pressure increased. The battle suits performed remarkably well as one- man submarines. This was accidental, but I was still proud of the design. When I’d planned the systems, I’d been thinking of the rigors of open space with all its deadly dangers. One of them was great pressure, of course. I wanted these systems to function effectively on high gravity planets, worlds with high atmospheric pressures and wild variations in temperature and radiation. I’d considered undersea combat, but only as a remote possibility. I had had no inkling that these suits would see their first real combat test under Earth’s own oceans.
“Any problems?” I signaled Kwon.
I heard a fuzzy, static-filled response. I cursed. I didn’t know how far away he was, but I’d hoped we would be able to converse over more than a few yards distant. I was immediately tempted to use sonic communications, but sternly forbade myself. I had to follow my own orders just like everyone else.
It had been such a long, sliding fall I’d almost forgotten to look for the bottom. Looking was futile in any case, as there was nothing to see outside the shaft of my suit’s chest lights other than more dark ocean.
