[Captain America - all media] So....when is Cap going to get a promotion?

Surely he has enough experience and a history of being a great commander to be a general by now. What gives?

In the zombie universe, he's a colonel.

Aside from that, 'Captain' appears to be an honorary term. During WWII, Steve Rogers was actually a private, albeit one tasked with secret counter-intelligence operations. In the modern age, Carol Danvers is known as 'Captain Marvel' even though she's a colonel. As such, we may conclude that 'Captain' is simply part of Rogers' codename, regardless of his actual rank.
