With the technology Wiete knew was at his fingertips. Technology many centuries ahead of anything any of the earth fractions or Mars-One could throw at him. No 'cat' would be a match for Wietse at this point.

I think these 3 sentences should really be just one long sentence, written as (with edits in bold):

With the technology Wietse knew was at his fingertips, technology many centuries ahead of anything any of the Earth factions or Mars-One could throw at him, no 'cat' would be a match for Wietse at this point.

The words "earth" and "fractions" were common issues/errors before, the other one in this chapter that has come up previously was "New-Zion" which should not be hyphenated.
