Tracking down the pilot was easy. Dialog xml file gives <pilot_name>, which you look up in
\Data\Game\Pilots.xml, which points to a string in
\Data\LocData\English\m_pilots.loc.
In this guy's case, just match the blue stuff:
1)
Dialog.xml: <pilot_name> -->
VksOfficer
2)
Pilots.xml: <GamePilot name="
VksOfficer">; and callsign -->
#M_pilot_Name_VksOfficer
3)
m_pilots.loc: #M_pilot_Name_VksOfficer = MSF lieutenant
(whom I renamed, as seen in the screenshot)
The pilot's icon, perks, and all other crap are in
Pilots.xml so if you feel like changing more stuff it's all in there.
