That'd be pretty interesting. I can't imagine him participating directly in the war but investigating strange reports from soldiers deployed to the area would be fair game and give writers a chance to tackle Vietnamese folk lore.
Given the BPRD's prior relationship with the Army I could see them calling in a favor and asking Hellboy to search for a missing unit or something.
1969 Hellboy's missions to Romania and Scotland according to the ''Hellboy Companion.'' ..If possible ( and Mike wants to go there) South East Asia is open for investigation with the Vietnam War as background and foreground...I didn't see this as a Sgt Rock story scenario, more a both sides are fighting with a neutral BPRD plus others as advisors
…..in the middle. ..A good luck mission impossible ..Could be a lot of fun ,Vietnamese legends, Geo Political intrigue and a lot of lead flying.....
This immediately came to mind...

Production values on that short were brilliant....I just watched the Ken Burns ''Vietnam War'' series as well. [ eye opening] I would have also liked to see the story from the perspective from the other 5 Nations who were there, and contributed.
