I actually rather like this character, it's an interesting take on the Mass-production infantry that I wouldn't have expected someone to do.
As far as I can tell you only really have one problem; MPI's don't actually receive training, since they are mass-produced, they are imprinted with skills and a basic personality upon creation and can theoretically go into battle as soon as they can stand. So, the whole basic training and socialization process that peacetime Nekos go through is skipped in order for the speed.
One major thing about these more quickly produced nekos; They are prone to psychological damage once they finally do achieve sapience, and any that live long enough often go crazy, or at least have some major mental problems, and existential crises.
Also, I'm just assuming that's only the beginning of the serial number, they make a LOT of MPI's, in the order of millions, and at one point they made billions at a time. (the previous war)
For the five required skills, it would be better if you used the Boilerplate skills (as in, as they are on the Wiki), but a bit of personalization is okay. your current one liners are not enough.
Other than that, as I said, your character is looking pretty good.
