Captain (land and air) 

I added the links because they were on the Captain (naval) page.  

Basically, I agree with you; however, I also think that the "Common military ranks" info boxes ought to also be deleted because they are not necessarily common to all nations, they have a footnote about the UK, etc.  Therefore, I think that the info box ought to be deleted also.  This was also a concern of an anonymous user back in Sept see Talk:Captain (land and air)).  Thoughts?
