There are still some kinks in the Common.css. It appears that the margin-left: -25px works ok when the tabs are encapsulated in an existing box (see Trooper) but not so well when broken out into their own pages (see Light Tank). I don't have permission to modify the Common.css, but a solution might be to place the Light Tank-style weapons inside a template.

Also the edit you made to Light Tank for tabview doesn't really do anything I don't think. I didn't revert it since it doesn't hurt anything either, but it might be unclear if anyone else came by.
