The Boys in Company C, directed by Sidney J. Furie, starring Stan Shaw, Andrew Stevens, Craig Wasson, James Canning, and Michael Lembeck, is a 1978 film about United States Marine Corps recruits preparing for duty, and their subsequent combat in the Vietnam War.
 It was among the first Vietnam War films to appear after the Vietnam Era, and was also the first role for R. Lee Ermey of "Full Metal Jacket" fame.

The Easter Offensive (Vietnamese: Chiến dịch Xuân hè 1972, or Mùa hè đỏ lửa, the "Red fiery summer" as romanticized in South Vietnamese literature) was a military campaign conducted by the People's Army of Vietnam (PAVN, the regular army of North Vietnam) against the Army of the Republic of Vietnam (ARVN, the regular army of South Vietnam) and the United States military between March 30 and October 22, 1972, during the Vietnam War.
 This conventional invasion (the largest offensive operation since 300,000 Chinese volunteers had crossed the Yalu River into North Korea during the Korean War) was a radical departure from previous North Vietnamese offensives.
 The offensive was not designed to win the war outright but to gain as much territory and destroy as many units of the ARVN as possible, to improve the North's negotiating position as the Paris Peace Accords drew towards a conclusion.
