That would make him late 30s, early 40s.
There is a Dan Love located(or previously) in San Bernardino that is 42.
In any case I withdraw my assertion that he is SpecOps. BUT it is clear he has significant training in the techniques they employ. I also put out on a email chain to Burners asking if they have any encounters with this guy. These are the people who make Burning Man work. The contractors etc.
Good one.
If he, or any of the other feds were mecenaries/foreign soldiers- Is that even Constitutional?
