The post is about how we should learn about leadership from the military. The US army is the mightiest military force in the world. But that's not enough to win wars. Winning wars seems more interesting than having great teams.
The blog post never says it is.

It's ok to write blog posts about a variety of things, even if you think there's something potentially more interesting elsewhere.
I would like to point out that having a great military force is not enough for what's important -- many times, it's not even needed!
This is a guide for those who have decided on their own that they want to focus on building a great team, because their personal assessment is that a great team is what they need to succeed.
