Landships II

How does one interpret the ratings?  Looks to me like there's a single critic who didn't rate it well on any aspect.  Well, I found it informative.  If that critic can do better, I would like to see hir work.

Incidentally, there's a link in there to David Kenyon's PhD thesis (late 2007)

BRITISH CAVALRY ON THE WESTERN FRONT 1916-1918.

337 pages without figures (omitted).  I'm sure it would stir much debate/comment should people be inclined to wade through it - seems quite dismissive of the tanks then extant.  Or maybe I got the wrong end of the stick in a brief skim?  It's not a document meant to be skimmed,
