Query: A GOOD BOOK TO READ TO UNDERSTAND THE USEFULLNESS OF THE

ELITE SNIPERS IN ALL WARS. THEY WERE THE FORCE TO EVEN OUT THE PLAYING FILED IN VIETNAM. I REALLY ENJOYED THIS BOOK, WITH ALL THE REAL ACCOUNTS OF ACTUAL SNIPERS DAY BY DAY ON MISSIONS AND HOW SNIPER TRAINING ACTUALLY BEGAN. BUT IT DOES VEER OFF THE MISSION TOPICS, AND GOES INTO A HISTORY LESSON WICH REALLY BEGAN TO BORE ME, BUT THEN COMES ANOTHER MISSION. AND IT MIXED EACH WAR DURING THE BOOK TOO MUCH, HE SHOULD HAVE WENT THROUGH THE HISTORY EACH WAR LIKE A TIME LINE OF EVENTS (WARS) AS THEY HAPPENED AND HOW EACH SNIPER FROM THAT SPECIFIC WAR ACTED. WHITE FEATHER IS TO ME , IN THIS BOOK THE BEST SNIPER, BEST INTELLECT ON THE ART OF ONE SHOT ONE KILL AS IT SHOULD BE!
