The offensive was particularly noteworthy due to its duration and ferocity as well as the extensive use of tanks by North Vietnam, a rarity during the Vietnam War. In this episode, retired Colonel Rick Cassidy recounts a battle and his role in it during this pivotal period, which resulted in him receiving a Purple Heart and the Bronze Star Medal for valor.

The massive fight that ensued would involve the other platoons of Meyer's B Troop, as well—matched up against an enemy force three times the size of their own.
