Extreme training and combat expertise are only part of what make the SEALs the world’s most effective fighting force. What truly sets them apart is their warrior ethos: a code of honor combining courage, discipline, and unhesitating willingness to risk life and limb to accomplish the mission or aid a fallen fellow soldier. This ethos has been tested like never before over the last two decades, with relentless, unprecedented periods of combat in which the SEALs have played out an outsized role. Many SEALs carry permanent injuries, and many have lost their lives–but none of them regret helping defend their nation and their brothers in arms.
