Do crew ranks influence the vehicle's performance?

In other words: Does the very same tank (or module) perform better when commander's and crew members' ranks are higher? Just wondering because pre softwipe the commander of my tier 7 already was a Major (with 70% into his 2nd secondary skill) while post softwipe I jumped straight into a tier 8 and now my tier 9 commander (with 100% in all secondary skills) only is a Captain.
