have to be careful in this outfit.”
“What else can it do?”
“Come outside.”
She followed me into the sunlight. Passing marines stared at me, and half the laser turrets swiveled to study me. I sweated for a moment. I was a new classification of contact to them-and possibly hostile. More turrets swung to cover me. I froze in place.
“Unit Six,” I radioed back to the shed behind me. “Transfer the configuration and recognition patterns for the new prototype battle suit to all laser turrets. Mark as friendly. Do it now.”
“Done.”
After a few more seconds, the lasers relaxed and went back to scanning the skies and tracking birds in the trees.
“That was close, Kyle,” Sandra said at my side.
“Yeah. I forgot.”
Inside the suit, I stood motionless for a moment. I was trying to figure out how to control the new system for my next test. I’d built this prototype unit with the same Heads Up Display we used in our regular battle armor, but for some reason it wasn’t responding.
“What are all these lights and lines for?” Sandra asked, walking around me in a circle. She traced various LEDs on the exoskeleton with her fingers.
“You need light in space,” I explained. “Both for identification and just to see. I can change the colors too, like this…”
The lights running over the suit changed from a soft blue to a soft green.
“Oh no,” she said, “change it back. I like blue better.”
I tapped through the color palette back to blue.
“How will you tell one another apart in these things?” she asked. “I think the colors should mean something. How about rank?”
“Good idea.”
“Blue for officers,” she said. “I only want to see you in blue.”
I laughed. “And the other ranks?”
“Red for most marines. Green for non-coms.”
“All right,” I said, liking her ideas. It would make the identification of my people easier in combat. I hoped the Macros wouldn’t figure out they should shoot the guys who were lit up in blue-but I didn’t worry too much. They didn’t seem like they were overly interested in colors and insignia. I didn’t think they really understood or cared about our command structure, which was very different from their own. Macro Command was a parallel- processing wireless network that consisted of every Macro in the region. They probably had no idea some of us were giving the orders while others followed them. In their social systems, everyone participated and instantly came to the same conclusion as to their next tactical move. In a sense, they were the ultimate egalitarians.
Sandra stepped back suddenly, looking up at me and smiling. “Okay,” she said. “Enough fooling around. Let’s see what this thing can do. Impress me-but don’t get yourself killed.”
I’d planned to work up to flight, but thought that now was as good a time as any to try it out. One of the major design goals for these suits was improved movement. Using the exoskeleton for dramatic leaps was only part of it. This battle suit had its own propulsion system. I’d placed propulsion disks in the feet and arms. The disks were miniature versions of the flying dishes my marines had rode into combat while boarding ships during the long flight home. With four smaller units, I hope to provide greater stability and more fluid maneuvering.
“Here it goes,” I said, and applied thrust. It took a bit more than I thought it would, but after a moment of trembling, I was airborne. I rose up over the base, slowly applying more thrust.
Again, I caught the attention of the laser turrets. They snapped their projectors around to sight on me like a flock of suspicious cranes. They slowly turned away, however, as I hovered there in the middle of the base. I was only using the two bottom propulsion units, the ones on my feet. I could feel them vibrate there, tickling my toes slightly.
“Wow!” Sandra called, clapping her hands. “I didn’t expect that. Go higher. How high can you go? Can you reach space?”
“No,” I radioed down. “In zero-gee, I doubt I could reach escape velocity, but I could maneuver freely in orbit. In an atmosphere with Earth-level gravity, I suppose I could fly around above treetop level indefinitely.”
“You should come down here and carry me. Like Superman.”
“Yeah,” I said. “Maybe later, after a bit more testing.”
“We’ll be dead by then,” she said, pouting.
“Maybe.”
I landed then, and tried running in the suit. Oddly, that was harder to manage than flying. Getting the rhythm right, pumping my legs up and down in the correct pattern at the correct time was difficult. I headed out to the forest and immediately ran into a tree. Bark chipped off showing the orange-white flesh of the tree. Soon after I stepped into holes and went tumbling. The test was a general failure. I could see the suit was going to take some getting used to. The problem was my natural body movements weren’t quite in tune with the weight and mass I was trying to move now. I had the strength, but it was as if I’d gained a thousand pounds and a lot of muscle. It was all about the timing.
Another major issue was the isolation and lack of tactile feedback. When running, the human body gives the brain input from our feet and limbs as to where they are in relationship to the ground. With this suit on-well, it was like trying to cut your toenails with oven mitts on. There were lots of accidents.
Sandra glided after me as I trotted around among the trees. When I fell, she helped me back up. After an hour or so, I was doing better. At least I wasn’t falling on my face and bumping into things all the time.
Sandra banged her fist on my metal-coated shoulder blade. I didn’t really feel it, but I heard it.
I turned smoothly to face her. “What?”
“Let’s shoot something,” she said. “I know you would never build a monstrosity like this if it couldn’t kill a Macro.”
“Have you got autoshades?” I asked.
She smiled and I watched as her eyes darkened. I’d forgotten about that. She’d had them built in. A nice trick. Maybe I could train my nanites to do that.
I turned back and aimed forward. I extended a gloved fist. Inside the arms, I’d build laser projectors. I burned down a tall palm with a single blazing emission and a slashing motion. The palm toppled over, the fronds at the top fluttering wildly as it fell. Birds screamed protests at us.
“You have two lasers?” she asked. “One in each arm?”
“Right.”
“You’re twice the man I thought you were.”
“So are you.”
Sandra gave me an odd look, not sure if she had been insulted or not. Fortunately, she couldn’t see my grin due to the glare on my faceplate.

A few days later I had all thirty one of my factories producing improved models of my new battle suit. The suits took about three hours to produce, but they didn’t take much in the way of specialized materials. After two steady days of production, I had about five hundred of these specialized suits. I’d already taken volunteer marines and set up specialized crash-training courses.
Crow came to watch me lead a company out on the beach a mile or so south of Fort Pierre. He stood on the beach with his arms crossed as we flew over the waves, shot hot lasers into the ocean and practiced diving through the resulting plumes of steam.
Finally, Crow signaled me impatiently. I ordered Kwon, who was assisting me in the training, to continue to lead the troops through maneuver and fire exercises. After that, they were to run ten miles through hip deep
