Personally, I find myself kind of disgusted by the directives given. They seem very high on pride and loyalty, and quite low on survival. I know mental backups can give the Star Army the outlook that life is cheap, but the reality is that for the majority of Star Army soldiers, their first death is also their final death. Not everyone gets respawned, especially when the ship they served on is destroyed. On plotships we have it easy because most of the time, we actually do get the plotship to survive (the majority of the time), so the luxury of reviving individuals is present.
But for most nekos, unless they are of high rank and were preserved elsewhere, they only get one life.
Given that context, the code of conduct displayed doesn't seem to give much of a damn about the life of the soldier that has to adhere to that. Past neko programming, since nekos aren't the only soldiers in the Empire, how am I supposed to feel the military cares about my contribution if it'd give up on my life so readily to uphold what most of all seems like pride and apparent infallibility.
You're given practically no way of surrendering as a commander. If you cannot win, that surrender is offered, and continuing to fight would just mean waste of life, why not grab the olive branch if its offered? Not all enemies are Mishhu.
And if you're captured, behave in ways least conductive to continued survival? Most especially, slap away any kind of humane/sympathetic treatment?
Being a prisoner of war isn't the end. If your opponent is the least bit respectable and/or fights while adhering to certain convention, you can survive to be freed later through rescue or even after the war is ended. You can be ransomed too or used in a prisoner exchange.

I've never served in the military, so perhaps I'm naive in consideration to this article and the outlook of members of a military. I'm also a little appaled that this has foundation on real stuff.
