If you like guns, really BIG guns, such as howitzers, artillery and railroad guns, here's your book!
Ian Hogg is the Master of all things that shoot loudly; a British artillery expert, veteran of the Royal Artillery, and a great story teller. He not only knows just about everything there is to know about shot, shell, barrels, carriages and such; he probably fired just about every weapon mentioned in his book.
Although this small book from the Ballantine Military Series covers large guns of World War II in very good detail, it is far from dry and overly technical. Mr. Hogg has written countless books on military weapons and he has a delightful dry British wit that makes you feel like you're reading something by P. G. Wodehouse. Hogg also takes no sides and passes out praises and brickbats to all countries products and gives credit where he feels it belongs.
Of course, this is a book about weapons of war and not everyone's favorite topic, but if you need a short and accurate summary of the artillery of World War II; you can't do any better!
