War Thunder: Crew Skills with Angry Nerd

I have been meaning to  do something like this and I still might.  Two main questions I get on War Thunder is how to do "crew skills" and why is the drive so "sloppy" - especially in early tanks.  For now I am linking a great video by "Angry Nerd".  I like a lot of his suggestions; however, I do not think there a one way that fits all. -armedbushido
