I can say those things based on knowing PSD job functions in Iraq, analyzing AARs, video, interviews, mapping locations of him, his teammates, and the threats, etc.
And I formed my opinion while actually conducting infantry operations in Iraq, performing the PSD role, and analyzing what went wrong with his element to learn from it. Everyone makes mistakes, but his were particularly bad and caused by the fact that he did not have the professional education nor experience necessary for the position he was in. He never should have applied for that job, but that’s on him.
He has limited real world experience (LE or PSD) and no military experience. And he has yet to show that he can handle a war zone.
