Schwarzenegger, also Pratt’s real-life brother-in-law, will play Donny Mitchell. Fresh out of training, Special Warfare Operator 2nd Class Donny Mitchell is James Reece’s baby-faced youngest team member. While the other guys crack jokes as a way to cope with what they’ve seen, Donny’s feisty sense of humor is different… he’s only seen the brotherhood of the SEALs in times of strength, not yet in times of suffering. As the platoon’s point man, he is the first to lead the team into unsecured territory.
