The Encyclopaedia of the Modern British Army is just that, it covers the weapons, organisation, uniforms and Insignia of the Modern British Army. The first Edition was published in 1980 and the Third in 1986 so it covers a good part of the later cold war period and looks backwards and forwards from the point of writing covering equipments going out of and coming into service. The book is written by Terry Gander an Ex RAF and Royal Observer Corps officer who has written extensively on AFV's weapons and military subjects for a number of major publishers including Janes.
It contains extensive organisational detail for teeth arm units breaking them down into sub units, troops and platoons and providing detail on vehicle holdings. Teeth arm units in this instance include; armoured regiments, armoured reconnaissance regiments and infantry battalions. The remainder of the army is covered descriptively but a lot can be derived from the text. A wide variety if not all in service systems are covered in the equipment section including those that had not quite delivered when the book was published such as MLRS, and Spartan MCT and some on their way out such as Wombat. In addition to the usual guns and AFVs it covers signals equipment, engineer equipment, radars and every conceivable truck - and there were a lot. From my experience the information presented seems accurate and it packs quiet a bit between the covers if you're wargaming cold war Brits it is a good second hand buy.
The second edition was printed in 1982 so the 3rd edition is the one to aim for as it covers pretty much the whole of the 1980s. Having said that I have a thought to chase down a first edition to see how the organisations changed. A search on amazon for Terry Gander also brings up some interesting titles of relevance to the period.
