Wing Commander III is unique in the series in many ways... and one you may not know is that it was popular enough that they actually dubbed the entire game in Korean! Dubbing games--especially in languages other than French, German and Japanese--was a rare and expensive thing at the time. Unfortunately, the actors that dubbed the full motion video are not credited in the game itself. AD recently found a very low resolution image that purports to show them and we've been attempting to use it to find the correct credits.
Here's what we've found so far! As you can see, we are still missing Tolwyn and the actor who did both Vagabond/Flash. If you can make out the image or you know more about accessing the Korean portion of the internet we'd love to know who they are! Our closest possibility for Vagabond/Flash is 황윤걸 (Hwang Yun-geol)... but we aren't confident enough to be sure.
Sadly, the actor that dubbed Colonel Blair, Park Il, passed away in 2019. If it helps the search, the Korean name of the game is "윙커맨더3".
