Excellent visual encyclopedia!

Book very clear and well illustrated. Many graphics very well explained. Sometimes some symbols are unclear but short articles help clarify. One may regret the impasse on some models of armament but in general everything is there. Large enough size so little advisable for a relaxing reading but to a table or a desk, or in a comfortable chair. For experts this book will not bring much, but for those who want to know more about the scope, range, rate of climb, the rate of fire ... it's great!
