Rebecca's suit can be seen as a more flexible heavy exoskeleton armor, with ultra-thick bulletproof steel plates and exoskeleton mechanical pressure-enhanced power.
It is configurable with multiple heavy weapons and micro-missile launch systems, hybrid petrol-electric powered, and can be seen as a 'Centaur Exoskeleton Enhanced Version'.
The AI fire control automatically calculates weapon trajectories, requiring only a neural cable connection to achieve easy aiming and shooting like using smart weapons, adopting Arasaka's exoskeleton-style pressure-boosting thrusters to provide a short-range high-speed maneuverable 'burst mode'.
It allows for solo flight for 10 minutes and can ignore bullets from standard specification weapons.
This heavy armor with a bulky appearance was named 'tank·1' by Mercer, also known as Tank No. 1.
The reason Mercer calls it a single soldier armor rather than an exoskeleton is because he discarded the previous design idea of 'mechanical force responsible for movement and humans just using the machine'.
Instead, he reversed it, with the design goal of 'mechanically cooperating with humans and the machine enhancing human physical performance'.
For example, if Arasaka's exoskeleton allows you to exert three parts of force, with the remaining seven parts being from the machine itself.
Then Mercer's design concept is to enhance human strength as much as possible. If you have a single arm strength of 500KG? His goal is to increase your strength to a ton without making you clumsy.
Achieving this is actually very difficult, starting with solving the problem of thought transmission.
Directly connecting a wire is like Arasaka's exoskeleton, it's hard to say how low the delay can be, the key is that your brain bears too much burden during control.
If you don't connect a wire and rely purely on mechanical drive, there will be more delay, like when you take a step forward and the machine suddenly adds a force... Overall, it's quite strange.
Fortunately, Mercer's design development was conducted simultaneously—when he solved the potential mental dangers of using the Octopus Arm, the thoughtfully designed thought conversion algorithm driven by AI for mechs solved this dilemma.
Mercer installed an intelligent core in each mech, and this core is akin to a small, portable high-spec computer host, dedicated to AI service.
Then, after the user's brain-machine cable connection, AI pre-reads the user's thoughts to perform synchronous transcoding and simultaneously drives the mech to cooperate with exertion.
In simple terms, when you're thinking 'left hand punch', not only does your left hand receive the command, the AI also synchronously receives your command and directly controls the armor to exert force by reading the neural signals controlling your arm.
From the perception of the human body, delays can be reduced to nearly non-existent and there is no feeling of controlling the equipment, because in fact, you are simply issuing a command, all operations are completed by the AI, and your nerves bear no burden.
For the user, the actual wearing experience of the heavy mech is more like wearing a hard, all-encompassing tight suit, with absolutely no operational delay.
Considering each set of mechs, even mechanical arms, requires such AI collaboration, Mercer simply named this AI, like Polaris.
'BT'.
This name comes from the intelligent AI of a mech in "Titanfall 2", where the full name of the AI in the game is actually 'BT72-74', which is simply referred to as BT by players.
During his gaming days, Mercer was moved by this life-and-death companion mech AI, so he borrowed the name as the designation for his mech AI.
When explaining it externally, Mercer would say BT is actually an abbreviation for BOT (robot).
Each mech's AI has its own number, starting from BT1-1.
These differ from Polaris, which resides in Mercer's main server, effectively running alongside the ctOS System and using server computing power as an independent AI.
Each BTAI is actually tailored for the armor set.
Because it needs to automatically record the host's usage habits, cultivate tacit understanding, optimize algorithms for the host, reduce delays, and match exertion. Over time, it can even exist independently as an intelligent combat partner for the host.
That is to say, each robotic AI is effectively independent, but Mercer does not grant them too much freedom in terms of permissions. They are born in the mechs and die with the mechs, apart from regular maintenance, they are not allowed to independently access the network to learn and enhance their intelligence.
The other type is the lightweight mech that fits the Sianwistan combat style.
Or specifically, the exclusive mech for V Zhen Tian—since she's the only one equipped with something like Sianwistan, and worthy of Mercer's significant investment.
This mech was named 'Falcon Spear Type-1' by Mercer, significantly reducing armor thickness, eliminating mechanical pressure boosting, and instead employing multiple micro compressed propulsion devices and electro-driven nanomaterial muscle enhancement technology.
Only a shoulder cannon is equipped for additional firepower, with the entire design approach aiming at developing peerless speed and agility to counter any foe.
This is to maximally exploit V's phenomenal reaction speed and physical agility.
The entire armor is extremely costly. Just the outer armor parts alone, due to reductions in weight while providing maximum protection, cost nearly 1.2 million euros because of the full use of the nanomaterial armor design.
Nanomaterial metal can be understood as a special metal with extreme toughness, self-healing ability, and excellent buffering capacity.
The nanomaterial metal's density is extremely high, yet its weight is light, just like laying a layer of subdermal nanomaterial armor under human skin that can block bullets, the whole set of nanomaterial metal can directly withstand small-caliber grenade launcher-level impact.
