For the casual modeler , I would say pick up the Osprey Vanguard or Squadron Signal books or Walkarounds on the vehicle your wanting to work on ( about $ 20 ) . Not a huge amount of technical info in 60 to 80 pages but enough text , drawings and photos to set you on the right path . A series called Nuts & Bolts goes into more detail on one vehicle or chassis type ( mostly German ) , getting down to ammo storage , engine compartment and radios , etc . Panzer Wrecks gives you pictures of wrecked / captured German vehicles , by type or setting , ie - Normandy or France 1940 . Ampersand Publishing has some great photo studies on the Churchill and the Staghound to name the two I have . Also Haynes , who publish auto books have a few on Military vehicles , I've got the Sherman , the Churchill and the one on Bovington's Tiger . My go to books for modeling ideas are Encyclopedia of German Tanks ( Chamberlain & Doyle- 1978 ) , British and American Tanks of WW2 ( Chamberlain & Ellis -1969 ). Old as heck , but with over 1000 pictures in the E of GT and over 500 in B & AT book , I get lots of ideas on crew stowage , battle damage , vehicle markings and general wear and tear on the vehicles . Lots of great books on Soviet tanks coming out of Russia , Poland and the Czech Republic , the only problem is that they might only have a short summary in English , the rest will be fun to translate , but lots of never before seen pictures , I picked up one , in Russian on the KV 2 . A great site to check out for modeling ideas as well as book and kit reviews is Armorama .
