Before SEAL Team or Six, there was a series that started it all. The Unit (2006–2009) was the first major television portrayal of a secret U.S. special operations unit inspired by Delta Force. With global missions, extreme training, and personal lives on the edge, it combined realistic action with a human look at the silent sacrifice of those who can never tell what they do.

The essentials: what it’s about and who’s in it

Created by David Mamet and partially based on the book Inside Delta Force by former operator Eric L. Haney, the series follows Sergeant Major Jonas Blane (Dennis Haysbert) and his elite team within an ultra-secret U.S. Army unit known simply as The Unit. 

Their missions range from hostage rescues to covert sabotage, but the series also shows what happens off the field: family life, isolation, pressure, and the impossibility of speaking about their work. 

Originally aired on CBS (2006–2009) 
Created by David Mamet 
Starring: Dennis Haysbert, Scott Foley, Max Martini, Robert Patrick, Audrey Marie Anderson, Abby Brammell

How they make it “credible”, key points 

• Direct military advising: Eric L. Haney, former Delta Force member, served as producer and technical advisor, ensuring that tactics, language, and procedures were authentic. 

• Missions based on real events: many episodes adapt or reinterpret historical Tier One operations, from rescues in Africa to missions in the Middle East. 

• Actor training: the main cast went through weapons handling, hand-to-hand combat, and tactical communication training. 

• Blend of action and domestic life: the series alternates between missions and the lives of the team’s wives and families, showing how secrecy and distance affect everyone. 
  
  

• Visual realism for its time: without excessive digital effects, featuring outdoor shooting and real gear adapted for TV (M4, MP5, M9, early multicam uniforms). 

Real curiosities (to share with friends).

• Based on the real Delta Force: the character of Jonas Blane is inspired by real operators from the 1st SFOD-D (Delta).

• The advisor was a real Delta: Eric L. Haney not only wrote the source book but also participated in every script to maintain military accuracy.

• Iconic theme music: the opening “Falling Through the Sky” and its anthem “The Unit” became the series’ hallmark, with a solemn and military tone.

• Cancelled at its peak: after four seasons, CBS decided not to renew it, leaving several storylines open just as it was reaching its most mature point. 

• Cult series for soldiers and airsofters: even today it’s used as a reference for its balance between tactical realism and television dramatization.
