I suggest changing the name Gun Elevation/Depression to just Gun Arc, as the name is occupying two lines in the infobox and making it very awkward looking. The - and + should be completely adequate to distinguish which one is which when you read it.
Gun arc means the rotation of the turret. I guess I could change it to Elevation Arc
If you guys need gun elevation and depression stats, I can give it to you
The numbers just need to be filled out in the articles. I made this thread because it would take me too long to do all of them by myself.
