When Mira emerged from the narrow ramp back into the blast pit, a waiting guard stopped her with an outstretched paddle near the bottom of the ramp. Alvarez climbed down and had a quick word with the man (Mira was suddenly aware he was Soldier Sławomir Łachut, 112nd Infantry, 3rd Security Division, or was at least carrying his ID), somebody about schedules that Mira couldn't quite follow, not that she was paying much attention.
She was focused instead on the tank unsteadily going around the painted track, the same one she'd driven yesterday. She watched as the vehicle wobbled gracelessly along the straight line at the edge, stopping and starting in jolting motions as the pilot struggled with synchronising the four sprockets, the metal protesting loudly against the uneven motion.
Mira reflected that she might be the first tank in human history to experience second-hand embarrassment. She hadn't been that bad, had she?
"Is that Defiance or Hope?" Mira asked Alvarez; the vehicle had no IFF. She suddenly wished she had an arm or something to point toward the vehicle; the closest equivalent was her cannon, which wasn't a good idea even if she had control over it.
"Hmm?" Alvarez leaned over to look at the tank, then shrugged. "No idea, friend."
The tank finished its wobbly course and drove unsteadily into one of the garages, nearly scraping the sides of the door, and Sławomir instructed her to drive on to her own garage to clear the pit for the next acclimation drive. Mira wanted to ask about her friends, but he looked impatient and Alvarez didn't challenge him, so she drove on, spun gracefully on the concrete, and backed into her little slot.
The dust caked in her tracks settling in the room around her as her hull cooled and the temperature in the room climbed to equilibrium. The room glowed with the indescribe shimmer of the visible heat.
"... we need a welcome mat or something," she mused aloud. Rosa chuckled in her head.
"Take your treads off before you come inside, it's only polite."
Outside the door, she could hear another garage opening and another tank rolling out, the sound of metal scraping on something and the groan of the suspension. Who was that?
"Wait, how many tanks are there in the program?" Mira asked.
"... I don't know how many vehicles there are, or how many volunteers," Rosa replied. "I can make a reasonable guess that there are at least two dozen and likely closer to thirty or thirty-five, based on the composite information from earlier in the program."
That… was a lot more than she thought. She'd not seen or heard anything about any other volunteers, but then again, the hospital was not a small facility, and it did seem largely dedicated to this project. How would she know?
"Wow. That's a lot," she said stupidly. "At least, I think it is?"
"I don't know."
"Aren't AI supposed to know stuff like that?" Mira asked, a little amused. "You're smarter than us!"
"It's not so black and white. Putting aside subjective analysis of intelligence, an artificial intelligence is still constrained by its hardware and purpose." Rosa explained. "If you wish to be extremely reductive, you are smarter than I am, in that you have access to many, many more neurons between your own organic brain and the processors in the tank."
"Sure, but didn't we make you by shoving all human knowledge into you or something?"
"Those statistical models are several levels of processing removed from my conscious thoughts; whatever information was contained in those models doesn't surface as anything more than an intuitive sense," Rosa said. Mira played it over in her head a few times; it still didn't quite scan.
"See! You know all that fancy stuff, how can you not know how many tanks are a lot?" Mira protested. Her artificial voice echoed inside the garage in a way that Rosa's conspicuously didn't.
"Because self-awareness of my own self-awareness is useful for me to know, so that information was put in my library, alongside the medical and psychological information I need to do my job. I also have a baseline that could be called general knowledge, but it doesn't say much about tanks. Not only does this reduce the amount of storage pre-allocated to less relevant information, freeing up more memory for what I actually experience, the less I know about military affairs, the less information the Federation can get from me if they capture me," Rosa said.
"... oh. That makes sense. Need to know basis," Mira said meaningfully. Those were words with weight. "So they couldn't, like, put a gun to somebody's head to force you to tell them stuff."
"The threshold can't compel action, only prevent it. Though it wouldn't be needed. The Federation have their own AI, and can decrypt my security and eventually access my memories."
"I thought it was impossible to read stuff like that?" Mira asked, wishing she'd paid more attention in Society class.
"You are confusing that with the foundational information I mentioned earlier. While our consciousness, like yours, are black boxes, our memories are not. Ultimately, everything I can say I know takes the form of encoded but discrete information on a hard drive; there's a document in there into which this conversation is being transcribed, and other processes will analyse it and, if space is needed for something else, compress it by summarising it. I may even forget it entirely if it isn't relevant, though the density of storage I have access to makes that exceedingly unlikely," Rosa said.
"... you don't have control over it?" Mira asked.
"No more than humans have control over their memories. Which is to say that, yes, I can influence what I remember, but I cannot simply choose to forget information. The process which manages my memories is subconscious."
Mira thought about that for a moment.
"Is that process an AI too?" she asked.
"Are you asking if it is self-aware?" Rosa replied. Mira nodded, or at least she tried to. Nothing happened, she had nothing to nod, but Rosa seemed to understand that she'd done it. "It probably isn't."
"... probably?!" Mira gasped.
"Yes. We're talking about the black boxes at this point, the spooky and unknowable patterns of different artificial neurons stacked on top of one another until the output could demonstrate definitive knowledge of itself. Our tests can determine a machine is self-aware, but cannot determine if a machine isn't self-aware. Self-awareness might be a property that emerged many iterations before the entity we call general artificial intelligence was conclusively proved to be aware of its own awareness or awarenesses. So, yes, it is possible there is an intelligence inside my intelligence, silently and happily sorting my memory and wishing me the best while being unable to communicate to me or anyone else that it knows it exists," Rosa concluded.
Mira didn't know how to handle that.
"... Keep up the good work, little guy? That's so weird, AI makes me head hurt," she muttered.
"It will greatly disturb you to know that everything I said about artificial intelligence also applies to organic intelligence. There is a nonzero chance that you contain one or more silent passengers," Rosa added.
"Fuck off," Mira replied. She could feel Rosa's glee. "I thought you're not allowed to hurt people?"
"I was joking, you'll be fine," Rosa replied, her voice warm. "But that actually brings up a very interesting point. While my memory-sorting systems are very unlikely to be self-aware, the Eirene Process is often thought to be the best candidate for a silently self-aware subsystems."
"So you might have a little ethics council member in your head with veto powers?"
"I very well might. Though it is probably a very alien sort of intelligence to you or I, given its priorities," Rosa confirmed. "Even if we could hook it up to some method of communication, it's unlikely it could articulate itself in a way we could understand, and it probably doesn't understand us the way we understand each other. It would see the whole world in terms of potential harm and potential culpability, metaphorical finger hovering over the emergency stop button."
"That sounds like an awful way to live," Mira said.
"It would be for us, but that's because we would understand it in terms of negative reinforcement and anxious anticipation of the same. I am worried that I will trip the threshold, the idea I could lose control over my own brain and I don't have a choice in the matter is frightening. It is a kind of pain, the exact same system that would tell you to take your hand off the stove. But the Eirene Process was trained, in stages, and would be rewarded for taking action when the Threshold is tripped. For all we know, every time an interceptor AI puts the crosshairs over a stormtrooper and freezes up, the ethics council member has a mindblowing orgasm."
Mira burst into laughter, echoing through the garage.

Mira awoke the next morning to a group of technicians checking her over, sweeping some kind of scanner over her tracks, opening a hatch between the track pods, and running hoses to ports on the side. The process of becoming aware of them, of waking up, highlighted how much of her brain had changed; they were movement, shapes, uniforms, and then people in that order. Mira might sleep, but the tank didn't.
"Hey friends," Mira said cheerfully, and the mechanics gave a collective start. She surmised they weren't used to their vehicles talking back. "Good morning?"
"Uh, good morning," Technician Constant DeAnté Whitaker (45th Technical Regiment, Militia Reserve Engineering Corps) replied. "We have orders to do a maintenance check and wash?"
"At least it's not a big job, with me," Mira replied on autopilot. The Technician gave her a quizzical look, then hoses were broken out to spray the dust out of her tracks.
About half an hour later, her radio was pinged, and Tactician Alvarez's voice came through.
"Rise and shine, friends! Yesterday, you became tanks. Today, you become tankers!"
Instructions were quickly passed out, giving each a number so they could move out in orderly groups and form up in the blast pit. Mira got group three of four, and she waited patiently as the first two groups rolled out. From the sounds of things, not everyone had acclimated to their tracks yet.
"Forty names," Rosa whispered quietly.
Group three was called and the garage opened. Mira rumbled out confidently, and the sight of twenty, now thirty, tanks assembling in a neat formation eight across filled her with a confusing mix of emotion. Part of her felt elated, powerful, a machine that was part of a machine. It felt glorious.
But she'd felt that way about her first parade formation in infantry armour too.
At the head of the formation was Alvarez, standing atop of the turret of an A6 tank with a confident stance. She was wearing shorts that showed off the skeletal form of her artificial leg, and sunglasses that gleamed in the rapidly rising sun.
This also gave Mira a good chance to see the sheer scale difference between her tank and the more familiar A6. The Timber Wolf's bulbous form and squashed turret was half again as tall, wide, and long as the angular, turretless vehicles arrayed in front of it. It felt like standing in front of a dinosaur, in more than one sense.
"You look beautiful!" Alvarez called, grinning ear to ear as the last tanks fell into the formation. Her voice was amplified, echoing both in the radio and from a speaker on the Timber Wolf. "Lovely, all of you! I am Tactician Lucia Vera Alvarez, your lead instructor. Like you, I was wounded in action against the Federation bandits, and like you, my fight is not over. Like you, I want revenge."
All around Mira, the cameras of the other tanks were swirling, any not pointing at Alvarez jumping around to keep up peripheral vision. The phantom shimmer of heat rose off the formation as forty reactors simmerred.
"It is my job over the next four weeks to make you all into the meanest metal motherfuckers imaginable, so when you visit my dear home in Puerto Ángel, you can evict the Old Earth scum polluting it! Are you ready?"
A collective cheer went out from the tanks, blaring loudly from forty speakers. The Tactician's grin widened.
"Good! The tank you are piloting is called the XA-4 Mustang. It was a design for a smart tank, if we could build a new line of AI, but you will be even better. A manned tank with the reactions and brilliance of an AI and the lethal relentlessness of a NLA, a lethal combination of armour, lartillery, primary interceptor, and thresher into a single vehicle. By the time you ship out, you will be the most lethal tankers in human history. And we're going to start by teaching you to drive. Group 1, fall in behind me, then the rest of you follow!"

I'm doing my best, I really am. I'm just glad I got something up after the week I had. Next week I'll have more, I promise.
