No; this is just an elaboration on the author’s concept to give perspective on where it may be apt or lacking.
The first word of your comment is "Imagine", then a bunch of description, then the last line is a summary of this imagined world. Ok, I imagined, now what?
You've taken a romanticized narrative of the military and then abstracted the terms so they could apply to startups. I can't engage with it as an analogy because it's an imaginary YC on top of an imaginary military. I can't engage with it as a position because you haven't made any claims outside the scope of this world you described.
P.S. I should also mention that I have zero clue what YC is like in present or past form, so I couldn’t competently draw a direct comparison, instead inviting the reader to make their own.
I think the more different the context, the more specific the ideas you bring over should be (the trend seems to be the more different, the bigger the idea). So instead of trying to tell me the value of communication, I'd rather know in detail how one unit handles debriefings. Then I can maybe pick up some tips or try the whole thing.
