Punisher MAX - The Complete Collection Volume One

When a mob hit killed his beloved wife and children, Frank Castle became the Punisher - an unstoppable one-man army waging war on every piece of criminal scum plaguing New York's streets. But do the Punisher's origins trace back even further?
In 1971 Vietnam, Captain Castle's platoon faces a Viet Cong attack - and to survive, he must make a grim choice. Then, Punisher's old partner, Microchip, long thought to be a casualty of Castle's war, resurfaces with a startling offer! Will the Punisher play patsy for the CIA? If not, will they let him walk away? And in a story ripped from the headlines, Castle must take on rival Irish gangs when a bomb goes off in Hell's Kitchen!
