Commander Kira wasn't aware of this. Though I like how the first thing Starfleet did to her was effectively demote her when she was going out of her way to take a special mission for them. The naval equivalent of colonel is a captain.
Kira was a major, then was promoted. The next step is Lieutenant Colonel, which is indeed the equivalent of Commander. And LTCOLs can often be just called Colonel.
