A renowned expert on British tanks, Robert Griffin, gives a fine account of all the gun tank variants (Mk.1 to Mk.11). The author has described the history as only one who has lived it can do. The book includes ORBATS (with callsigns) for a Chieftain regiment in the early 1970s and again in 1989, plans for a Mk.3/3 and a Mk11, and a fine selection of over a dozen color plates of Chieftains in British, Iranian and Kuwaiti service for the modeler. The Shrivenham Mk.11 gets the full walkaround detail treatment with lots of detail shots and there are plentiful developmental and in-service photographs of all the gun tank versions.
