That’s Sgt. Brian Jackson of the California National Guard.
He posted this Facebook photo on June 2 while deployed to police Black Lives Matter protests in Los Angeles.
It shows him standing in front of a military vehicle inscribed with a slogan for the Proud Boys, a white supremacist, neo-fascist group. They are deemed a hate group by multiple organizations.
His Facebook page shows that he is a member of the group.
