Alvarez directed her toward a square slab protruding from the dirt, which turned out to be an observation bunker of some kind. She hit the brakes a little too hard as she rolled up next to it, still uncertain, and Alvarez slipped a short way down the sloped front plate, laughing.
"I can tell you're not much of a driver," she said, pushing herself up and hopping down; Mira involuntarily backed up about two feet, nervous about having a person directly in front of her. "Let's run you through the sandbox a few times so I can see how the track's held up."
Alvarez opened a hatch in the roof of the bunker and dropped in; a few moments later Mira felt a strange nagging feeling at the back of her brain that directed her attention to the map in her head. There was a topographical layout of the course, and as she watched arrows traced across it, clearly being drawn on in real time, then Alvarez reemerged from the hatch with her tablet out and a headset on.
"Okay, friend, I've marked out a course, drive it nice and slow for me and just tell me how the ground feels," Alvarez said, her voice echoing as it came through on the radio and external microphones simultaneously. Mira dutifully backed up and drove across the field, feeling her suspension flex as she passed over the small ditch at the side of the path and pulled herself up the berm on the other side.
The ground here was deceptively uneven; it had looked much flatter from the road, but it was an illusion created by the mottled texture of the lichen clinging to everything. Hidden behind the low hills was a twisted maze of worn and partially-overgrown paths, with what looked like a long firing range bulldozed flat at the far end. A small park of support vehicles had been left in the shadow between two hills, covered over with a tarp; she spotted the articulated crane of some kind of engineering vehicle emerging from under it.
She spotted another destroyed Federation tank on the range that had clearly been used for target practice, holed in so many places the rusting steel had curled in on itself in places under its own weight. It looked like it had been smaller than the other one even before it had been so thoroughly destroyed.
"That thing's huge," she commented. It had looked huge to her the first time she saw one; they had a reproduction at the training camp she'd gone to, alongside a number of other Federation vehicles, so the cadets could learn where their cameras were, see their blind spots, and figure out how to climb up onto them.
That had seemed insane, but the tanks had AI-controlled active protection systems which would stop any rocket big enough to knock it out. What they sure as shit
wouldn't stop was a nineteen year old in power armour; they showed them all a training film where a little slip of a woman put the hardened pickaxe end of her entrenching tool through the hatch of a captured Federation tank in a single swing, then pulled it straight off the hinges. The three-inch steel pin holding it in place broke like it was made of chalk.
"That's you," the narrator had said. "That's the power in your hands now."
"Don't be intimidated. They're bigger than an A6 too, but the first time I ran into those things in mine we killed two of them in thirty seconds," she boasted. "I had six to my name by the time I got hit, and it wasn't even one of them that got me. I'm just jealous you'll probably stack even more."
Mira pivoted onto the marked course, and found she could sort of see it in front of her. It wasn't like the heads up display in her infantry armour, it was more subconscious than that; nothing looked different, but parts of the dirt registered to her brain as being on the course and other parts didn't. She just followed the worn and dried track ruts and did her best.
She accelerated and began along the course, spraying up dust behind her in an enormous cloud. She narrated to Alvarez as she drove, but she felt woefully unprepared to explain the sensations; she didn't know what she was looking for, but apparently she was doing a good job, because Alvarez just encouraged her to drive on.
She came around a corner into a section of the track that dipped between two berms, with wires stretched across it, too low to pass. She ducked involuntarily as she slowed, and to her surprise the vehicle
actually ducked, her perspective lowering enough to pass under it. As she came out the other side, she experimented with that more; she was able to individually raise and lower each track pod on the suspension arm,
and the three road wheels in each pod, the tension on the track automatically adjusting as she leaned back and forth or raised herself up to peek over the side of the berm.
She came to a part of the path which featured two sets of two ninety-degree turns in a row, creating an odd zipper pattern. The ground looked strange here; the overlapping track ruts simply stopped, and instead the short path between the two turns was heavily churned.
She mentioned that uncertainty as she inched forward, and Alvarez's voice lit up over the radio.
"Oh, you're going to love this. Drive up, but don't turn yet," Alvarez instructed. Mira did as she was told, awareness of the possibility making it strangely intuitive, and felt her perspective rise slightly as she did with a clunk of metal. She craned her cameras over as far as she could, but couldn't quite see what was happening.
"Okay, what now?"
"The tread pattern on your tank has embedded casters in a diagonal pattern. They're arranged so you can do a little trick; try reversing and accelerating your diagonally-opposing sprockets."
Mira threw the tracks into motion, and she
slid, carried sideways on the broad tracks. The ground churned and dust exploded into the air in a vast cloud, despite the fact she was moving at a crawl. She hit the brakes, already disoriented.
"What the hell?"
"Ha! That's why it's a quad track; you can drive sideways. It was trialled on the Timber Wolves back in the day, but regular drivers couldn't get much use out of it, too much to manage. You should be able to get some good use out of it."
Mira advanced forward to the next bend and tried again in the other direction, though she misjudged her speeds and found herself both sliding and pivoting at the same time. She soon worked out she could do that on purpose, though, and before long she was gliding naturally as she moved, letting herself drift into turns with minute adjustments as she went around the course. And she could go sideways
fast, if she really pushed the motors.
"Just a heads up, don't do it on pavement, at least not pavement we want to keep. The tracks already do enough damage to roads," Alvarez warned. "Plus, that means more maintenance time for you, if you-"
She was cut off by an awful, staccato rattle from her rear left track and the feeling of her sprocket spinning wildly. She glanced back, a side camera extending to assess the damage, but the track was still
there; it was just turning slowly as the sprocket rattled against it.
"... yeah, that. You've thrown a track. Raise the pod, ratchet down the tension, cut in the track realignment system, and then run it nice and slow, it'll realign everything," Alvarez explained. Once again, just learning she
could do something seemed to make it possible; she lifted the track off the ground, tilting the suspension on the other three to shift her weight, and let the tensioner unwind, pulling in the idler. The track sagged off the bottom of the road wheels, then she slowly ran the track around; there was a
clack clack clack as some system inside the little box at the top of the pod realigned. She didn't know how it worked, but she pictured a zipper.
"This is so cool," she said.
"Yeah, it just puts a lot of strain on the hydraulics, and you
can't fix that out in the field. You'll be getting nightly tune-ups during training, and basically any time you're not running; get used to it."
"No worries, friend, I
am used to it. This is still way better!" Mira replied. She hadn't been able to
clean herself for two goddamn months, nevermind do anything at all if something went wrong. She had to ask for help if her glasses were too far away on the bedside table!
"... oh. Good," Alvarez replied. "Just take it easy with the crabbing today; rough dry ground like this is the worst place to do it, because the friction is high and the casters can't do much."
"Got it. Uh, why is our course here, then, if the ground's bad for it?" Mira asked.
"It was a lot better in the wet season. But hey, it's spring on the front at Puerto Ángel, so you'll be able to crab to your heart's content there," the Tactician replied, a bit if tension in her voice. "Now, let's see how the moguls have held up."
Mira drove on, cresting over (and tearing up) the dusty bumps, thinking hard as she reported on their condition.
"Something has you bothered," Rosa commented quietly. Mira remembered to use her external speakers.
"Yeah, can you blame me?" she replied, and waited for a response. It took a long time.
"I don't know, Mira. I told you, I can't actually read your thoughts," Rosa said eventually. "If you would like me to guess, you're worried about your friends in the program."
"... no, but kinda," Mira replied. "It's… why am I here, and Alvarez is out there? She's a veteran tanker, she's too disabled to fight and hates that, and she's
from Angel's Bay, only locals call it that. You'd think she'd be first in line!"
That characteristic pause. She'd said something Rosa needed to be delicate about. She was vaguely pleased by that.
"... Interesting activity there in your ventral striatum, Mira," Rosa cut in slyly.
"Huh?"
"You're happy about something, and I presume it's the fact I have to think about this one," Rosa explained. "Before you ask, yes, that is what I'm doing. I need to run and assess a nested series of adversarial simulations in response to ethically complex situations."
"Because of the Eirene Threshold?" Mira guessed.
"No, I do it because it is important I give you good answers. Though this analysis does help me avoid tripping the Threshold; it's a real risk when I hold a position of power and trust like this. The Threshold doesn't function through active analysis. It's closer to a reflex, like blinking in response to a bright light. Does that make sense?"
"Nope. Do you have an answer yet?" Mira replied, pivoting around at the end of the course and going back over it as instructed. She couldn't quite have two conversations at once, but she fully understood the orders Alvarez was giving and could acknowledge it while listening or speaking to Rosa. Yet another sensation Offline had no words for.
"I have for a while, we got sidetracked. I can tell you that Lucia Alvarez was a previous candidate in this program. She washed out. I cannot give you specifics due to both security protocols and doctor-patient confidentiality; most of the details are redacted from my memories anyway," Rosa explained.
Mira pivoted her cameras back to the distant figure of the woman sitting in the open hatch of the bunker. The detail jumped as she focused, showing her casually leaning against it with the tablet propped up in her prosthetic arm. She was regarding Mira with an inscrutable look, leaning forward a little as she spoke. Hang left and cut across the field, check for big rocks that might be a danger on manoeuvres. Got it.
"Huh. I wouldn't have guessed, she seems to be fine?" Mira asked.
"Again, it wouldn't be ethical for me to comment," Rosa replied neutrally.
Mira gave a mental shrug and continued along, counting rocks. It was a big field, under a big beautiful sky, the sun already beginning to descend toward the enormous, crumbling plateau. Mira could make out Tadmor in the night sky now; on Horizon 'other planets' were just bright stars in the night sky, but this was a
planet.
"How's the field, friend?" Alvarez reminded her.
"Looks pretty clear? There's a big rock about a hundred forty metre bearing 240 from my position, but it's buried deep, I could probably climb it no problem," Mira said, scanning for anything else. Mostly just more lichen; she felt a little guilty she was squishing so much of it with her tracks, but she heard that lichen could survive in
space, so maybe a tank wasn't a big deal.
"Mmhm. Keep going, we're gonna do formation driving here and, as I said, repairs are a bitch," she replied. Mira ploughed on happily; she was pretty sure she could do this for hours. Two hours ago she couldn't drive a straight line without focusing, now she was sideslipping on the casters on purpose. "So, uh, you enjoying the tank?"
"Are you
kidding? I'm having a blast!" Mira replied, sliding to a stop at the edge of the field, pivoting a bit hard to throw up some extra dust, and setting off again the other way to scan the ground more.
"That's good. Go out to, uh, the 093 boundary or thereabouts? That should be enough," Alvarez said. Mira's mental grid map placed that about a kilometre north; easy!
She drove off in her zig-zags as the sun descended, the huge gas giant and its attendant moons chasing it toward the horizon. She sped up perhaps a bit more than she should have a few times, wondering how fast she could
really go; she didn't feel like she was anywhere near her limits.
She reported a few more jagged rocks, as well as what looked like a discarded track link and some other debris. She also came across the remains of a dirt road and a crudely-demarcated soccer field; Alvarez said it was from some surveyors when the base was established.
"So, the nurses and stuff been treating you okay, friend?" Alvarez asked eventually.
"Mostly, yeah?The techs during integration were kinda…" Mira struggled to think of the word. "... cold? But honestly, people are too worried."
"What do you mean?"
"Everyone treated me like I was signing up to get tortured or something, asking if I was okay, making sure nobody was forcing me. But like?" Mira hit the brakes, sliding to a stop, pulsing the tracks on one side to skew her over and then rolling opposing pods with the movement, sliding across the dirt on the casters. She felt like a figure skater! She sped up one side and slowed the other, pivoting, adjusting her speed until she was smoothly driving backward, in full control the whole time. Two days ago she couldn't sit upright, now she could
dance.
"You okay? That was a lot of dust," Alvarez commented. Mira suddenly remembered that normal people couldn't actually see much from almost two kilometres of broken ground away.
"I did a cool spin," she explained.
"Ah. Glad to hear it! Just try not to wreck the tank."
Mira slowed down, back to her count. It was only once she was almost right up to the grid line that she realised something was off. Surely, if this mattered, they would have done this at some point? Couldn't an AI have done this with a survey drone? She'd been having so much fun, she hadn't questioned why she was doing it.
"Hey Rosa, this is busywork, right? A run for headlight fluid?" she asked, keeping her voice down. Just in case the technician developed super-hearing.
"Yes," Rosa replied instantly.
"... how long have you known?"
"Since the highway. She's attempting to assess your psychological state, rather crudely to be honest," Rosa explained. "I didn't tell you because you need as much driving experience as you can get, and you were enjoying yourself. I didn't want to ruin that."
Mira turned and started the final leg of the scan.
"Yeah, good call. What's the odds she'll let me go full-speed on the way back?" Mira mused.
"Very good, provided you ask first."
Mira's internal speedometer hit eight kilometres an hour on the way back. She wasn't pushing it.

Bit of a retcon on the tank design, I'll correct the older descriptions when I can. Also, sorry these have been growing shorter; I've been having a lot of trouble focusing this week.
