None of the troopers carry an E11 on Ferrix. Also, In my opinion, the backpack should not be included. That trooper is a completely different look. No armor, etc. I would go as far to say it would be a completely different CRL, as he wears no armor at all. But also, as far a I know, we only see half the backpack, so completing it might be nigh impossible as it is.
If it were me, I would keep this armored security trooper separate from the soft goods only variant. It's not quite as interchangeable as the Aldani troopers are, who are seen in many forms of dress. Here they are either fully armored, or in soft goods only.
Just my two cents.
