Deletion of T99 Heavy Tank

Comment: as not |notable lacking |significant coverage. This appears to be a planned tank, a concept of a prototype, along the lines of the T101 and possibly a second type of project. I would not be against merging this, possibly along with T101, to T29 Heavy Tank if the tanks are actually covered in the provided source. I got tired of looking because it was lacking a page number. I struggle with there being a desire to have very short under-sourced sub-class articles when it seems they could be incorporated into a parent article giving expansion and most likely a better class
