Joseph Picard was a teenager when the Japanese attacked Pearl Harbor in December 1941. Unlike some of his peers, Picard was neither excited to join the service nor dreading it. He just accepted that he would need to serve.

After completing basic training, Picard was assigned to the 552nd Field Artillery Battalion, working with the massive 240mm guns. The battalion was held out of D-Day operations and landed at Utah Beach in late June 1944.

In this edition of Veterans Chronicles, Picard takes us through all the work involved in assembling and operating the 240mm guns. He also walks us from Utah Beach through the Battle for St. Lo and the Allied drive to Paris.

Picard also describes the devastating combat at the Battle of Aachen, losing his best friend in combat, and the chaos and bitter cold at the Battle of the Bulge.

Don Graves tried to enlist in the U.S. Marine Corps the day after President Franklin Roosevelt declared the Japanese attack at Pearl Harbor a day of infamy. Since he was only 16 years old, Graves had to wait another six months to enlist. When he did, he went through basic training in California and was soon assigned as a flamethrower operator in the 2nd Battalion, 28th Regiment, 5th Marine Division.

In this edition of Veterans Chronicles, Graves recounts the harrowing landing during the third wave at Iwo Jima, getting pinned down in the water, what they had to do to reach the volcanic ash beach, and how he begged God to spare his life as the bullets flew above him.

Graves also tells us about the fight up Mount Suribachi against Japanese forces with the higher ground. He explains what made the difference in the fight, a shocking encounter with a Japanese soldier during the battle, and what he remembers about the iconic flag raising atop Mount Suribachi.

Then Graves details an even more intense fight at Hill 362 A, where his unit lost all its remaining officers. He also takes us into the fighting in the caves, both with guns and with his flamethrower. And he shares one of the most devastating moments of the battle that took place in his own foxhole.

Finally, Graves describes leaving the island alive when so many other Marines didn't. And he remembers hearing the news of the Japanese surrender just as he was training for the invasion of Japan.

Ed Hiner had no intention of joining the military until a friend's father forced him to help a military family in need. During that experience, Hiner met a Navy SEAL, learned about what the SEALs do, and immediately knew that's what he wanted to do with his life. Hiner joined the Navy, qualified for BUD/s training, and was one of just 10 SEAL candidates in his class to graduate.

In this edition of Veterans Chronicles, Hiner takes us through BUD/s training - from how his life abruptly changed the moment he arrived at Coronado to the mental toughness required to survive to his absolute refusal to quit. 

Hiner shares stories from his deployments to Iraq, including a high-profile mission thrust upon him as soon as he arrived and capturing the notorious "Butcher of Ramadi."

He also talks about the value of restraint in combat and why not using lethal force often saved a lot of lives and trouble.

Patrick Zilliacus was born in Finland and came to the U.S. when his father became the Finnish military attache in Washington, primarily to procure weapons for Finland's war with Russia. Left on his own in the U.S. at age 16, Zilliacus worked in a steel mill before joining the U.S. Navy in 1943. He was assigned as a torpedo man on a brand new submarine, the USS Spot.

In this edition of Veterans Chronicles, Zilliacus explains how he was almost killed when the USS Spot went out for "shakedown" after commissioning. He also details what it was like stalking and attacking Japanese vessels off the coast of China, and how his sub sunk the Nanking Maru.

Zilliacus also tells us what it was like to be pursued by Japanese ships, how the Spot was very close to a major event at the end of the war, and what his future wife told him about Japanese atrocies committed against her family in the Philippines.

He also shares the story of how his father crossed paths with a major Axis leader long before World War II and why he does not want World War II veterans to be called the Greatest Generation.

Ltt Gen. Marc Sasseville was born into an Air Force family and that played a significant role in his decision to attend the U.S. Air Force Academy and become an Air Force officer. After 14 years on active duty, Sasseville shifted to the Air National Guard in 1999 and also became a commercial airline pilot.

On September 11, 2001, Sasseville was serving with the 113th Wing of the District of Columbia Air National Guard at Andrews Air Force base when Al Qaeda terrorists hijacked four airliners. Once the second plane struck the World Trade Center, Sasseville and everyone else on base knew it was a terrorist attack. But would there be more planes? And would they be headed for Washington, D.C.?

In this edition of Veterans Chronicles, Gen. Sasseville tells how that day unfolded. He explains what development required pilots in the D.C. Air National Guard to scramble their F-16's and be ready to confront any other other planes being flown by terrorists. But they had a big problem. None of their F-16's were armed with missiles and there was no time to wait for that. The reality soon hit home: if they needed to stop an airliner, they'd have to hit it with their own planes. If that was required, they would not be coming home.

Sasseville takes us through his thinking on the most effective way to strike an airliner with an F-16. Ultimately, that would not be necessary due to the heroism of the passengers aboard United Airlines Flight 93. Sasseville honors them and he tells us what it was like flying near the Pentagon not long after it was attacked.

He also reveals the unexpected assignment he received later in that day on 9/11 and details his time as commander of the 410th Expeditionary Operations Support Squadron in the early days of the Iraq War. Finally, he reflects upon what was really asked of him on 9/11 and his instinctive willingness to put his life on the line to protect our nation.

Andrew Card served more than five years as White House Chief of Staff for President George W. Bush. Less than eight months into Bush's first term, Al Qaeda terrorists hijacked four U.S. airliners. Two were flown into each of the twin towers of the World Trade Center. Another was used to crash into the Pentagon. The fourth plane was headed to Washington, but was forced down in a Pennsylvania field by the heroic passengers of United Flight 93.

In this edition of Veterans Chronicles, Mr. Card takes us moment by moment as he learned the disasters in New York City were actually deliberate acts of terrorism by Islamic extremists, told the president the news in a Florida elementary school classroom, gave orders to get Air Force One ready to depart early, and figured out where they were going next.

He also takes us inside the intense debate he had with the president about whether to return to Washington and the first decisions Bush had to make, including whether to shoot down airliners refusing to obey air traffic commands.

Card also discusses President Bush's speech after returning to the White House, his impromptu message to Ground Zero recovery workers  on a bullhorn, his emotional meeting with first responders and families of those lost on 9/11 and much more.

We'll also hear why Bush asked Card to take one high-ranking national security official "to the woodshed" and the shocking thing British Prime Minister Tony Blair told Card after Bush's speech to a joint session of Congress. And we'll learn how both Bush and Card were scolded after Bush said he wanted Osama bin Laden captured "dead or alive."

Timothy Brown was serving as supervisor of field operations in New York City Mayor Rudy Giuliani's office of emergency management on September 11, 2001. He was already at work near the World Trade Center when terrorists flew the first plane into the North Tower. He was in the lobby of that building when he got word that a second plane controlled by terrorists struck the South Tower. He immediately rushed over there. Less than an hour later, the South Tower collapsed while Timothy Brown was still inside.

In this edition of Veterans Chronicles, Brown walks us from when he heard of the first attack through the horror of the South Tower coming down all around him. He explains what it felt like and sounded like as 110 stories crashed down around him. He also describes emerging from the rubble and getting out of the area just as the North Tower came down.

Brown believes his life was spared in order to share the heroic actions of firefighters and other first responders on 9/11. And he tells multiple stories of those heroes, many of whom were friends he lost that day. 

Finally, Brown offers his thanks to the veterans who took the fight to the terrorists in the wars following 9/11.

Christopher Brewer grew up as an Army brat and enlisted in the U.S. Army in 1973 because he wanted to be a Ranger. Even though he had never jumped out of a plane prior to joining the Army, Brewer learned quickly and passed the rest of his training to become a Ranger. He later took on and successfully completed intense training while serving overseas that served him very well in Special Forces.

In 1989, he was deployed to Colombia to assist government forces fighting against the drug cartels. The next year, he was in Panama, dealing with the volatile aftermath of Operation Just Cause.

In this edition of Veterans Chronicles, Major Brewer walks us through his intense training as a Ranger and in Platoon Confidence Training. He also takes us moment by moment on the training mission where his primary parachute failed and it took every bit of his expertise to survive.

Then Brewer takes us to Colombia, where he could not officially serve as a member of Special Forces. He explains what the overall mission was and his critical efforts to thwart drug kingpin Pablo Escobar from attacking and destroying an American radar station.

Finally, he tells us about his deployment to Panama, confronting unrest from many different directions, sniffing out intelligence about a possible coup attempt, and dealing with turf wars within the military.

Brewer is the author, most recently, of In the Shadows Between the Wars: Becoming a Special Forces Operator.

Tom Young grew up on his family's farm in North Carolina. From a young age he was fascinated by his grandfather's stories of being part of a bomber crew during World War II. That helped to spark his interest in both flying and in service. Young served in the Maryland and West Virginia Air National Guard, serving as flight engineer for C-130 Hercules and C-5 Galaxy transport planes. Missions took him to the war zones in both Iraq and Afghanistan. He is also a military novelist and his latest work is The Mapmaker, which focuses on the French Resistance during World War II.

In this edition of Veterans Chronicles, Senior Master Sergeant Young tells us all about the C-130 and C-5, his role of flight engineer during flight, and coming under enemy fire in both Iraq and Afghanistan.

Young also takes us into the world of the French Resistance, how it was so creatively organized, and the critical role it played in helping the Allies before and after D-Day. He also talks about how dangerous it was to be part of the resistance, especially in the face of the speakable cruelty of the Nazi Gestapo and SS forces towards the people of France

Hilbert Margol was the first of twin boys born to his parents in February 1924. He was nearly finished with high school when the Japanese attacked Pearl Harbor on December 7, 1941. Soon, Margol and his brother, Howard, were in the Army, training on 105 mm howitzers with the 42nd Infantry Division. They saw their first combat in southern France in January 1945. After that, they fought into Germany, crossed the Rhine River, and helped liberate the Dachau concentration camp near Munich.

In this edition of Veterans Chronicles, Margol explains how his Jewish family was very concerned about the advancement of Nazi forces and ideas long before the U.S. was at war with Germany. He shares the concerns his family had for loved ones in Lithuania and how he learned decades later about the horrible fate they suffered.

He also tells us how his mother's letter to President Roosevelt kept him and his brother in the same unit. He also describes his training on the howitzers and what his first combat experience was like.

Finally, Margol goes into great detail about how he and others discovered the Dachau concentration camp in April 1945, what he saw there, his tireless efforts to share the truth about the Holocaust, and how it deeply impacts him 80 years later.
