In 2005, Jeff Marshburn was a reconnaissance platoon leader in the 4th Battalion, 23rd Infantry Regiment, in Mosul, Iraq. While leading his platoon during the battalion's first contact with the enemy, several of his troops were wounded in action. In this episode of The Spear, Jeff recounts the lessons learned from his many combat missions in Iraq, with an emphasis on trust, competence, and the value of pre-deployment training.

In 2010 Kevin Mott's unit arrived in Afghanistan's Kunar province for a deployment that would see months of hard fighting. At one point, he was even wounded so badly—shot in the head, four fractured vertebrae, a broken leg, a torn labrum—that he was sent back to the United States for medical care. Several months later, he managed to be cleared to return to his unit in Afghanistan. After he did, the battalion conducted a mission aimed at clearing an area known to have a strong Taliban presence. Kevin shares the story of his platoon's heavy fighting as they worked their way toward their objective of Barawala Kalay.

In 2004, Tim Strabbing was a lieutenant and platoon commander in the Marine Corps, deployed to an area just outside Fallujah in Iraq's restive Anbar province. On his platoon's very first patrol, they were ambushed by enemy fighters, earning his Marines a baptism by fire and setting the tone for a difficult deployment ahead. He joins this episode to share the story of one particularly eventful 48-hour period.
