In 2004, Nathan P. Butler wrote the short comic book story Equals and Opposites for Dark Horse Comics' Star Wars Tales #21. The story, featuring Kyle Katarn and Jan Ors (both of Dark Forces / Jedi Knight video game fame) against the Yuuzhan Vong (The New Jedi Order), was later re-released as part of the collected Star Wars Tales, Vol. 6, then separately as a Hasbro Comic Pack with action figures.

Star Wars Tales #21 Comic Pack
featuring Kyle Katarn and Yuuzhan Vong action figures

Kyle Katarn and Jan Ors must join with Imperials under Lieutenant Pallin on Ord Sedra to fend off the Yuuzhan Vong and their Peace Brigade collaborators. This single-issue is the only variant to include only the Equals and Opposites story. It is included in a Hasbro Star Wars comic pack with the second Kyle Katarn action figure ever, and the very first Yuuzhan Vong action figure ever produced.

This version of the story is the hardest to find. I would suggest trying Ebay.
