Had 50 battles in the Colorado, very impressed by this ship. A true brawler.
Guns: good accuracy, hard hitting shells, over match all same and low tier BB bows.
Protection: Strong armor, strong heal, low citadels.
Small turning circle, and it is a short ship
Torp reduction 37%
Low HP (partially mitigated by armor and heal)
However if you take a central position, you are a big threat to almost all ships on the map. I used to stop at the NM during the US BB line grind since I have heard a lot of bad things about the Colorado. Now it appears to be a true gem in the US BB line, I would say it is the 2nd strongest BB tier for tier in the line, just behind the NC.
