In search of my Fiance's father who served in the Korean War. ON his gravestone, it says the 411th CML SG CO...I believe it means Chemical Smoke Generator Co. The problem is I am finding NOTHING anywhere about this particular Chemical company. If anyone has any info about this unit, please let me know. I'm thinking that perhaps the unit was part of another unit. My Fiance believes he served in Germany when they were reconstructing the country after WW2...other than that, I have NO other information.
