More like tragic - but it really did happen. And American combat officers had no choice in the matter. U.S. forces needed fillers, and the agreed solution was ROK troops. Unfortunately, there weren't enough of them so South Korean civilians were essentially impressed, given a few days (sometimes) of a sort of orientation and assigned to American units. This began in August, 1950. Obviously, the ROK fillers generally lacked English language skills, and had no uniforms or weapons. In fact, most had never touched a rifle. Because 7 ID had been stripped to supply fillers for other units it received the most ROKs and felt the most effects.
That particular phase of the experiment was generally disastrous and for a while it looked as if no more ROKs would be assigned to American units, but manpower requirements never let the program be abolished. There were ROKs assigned to American units into at least the mid 1960s. However, by the middle of the war most of them were receiving at least some training that could legitimately be recognized as basic military training, and their quality improved.
This sounds rather ridiculous. The ROK Marines were pretty good troops, but the ROK soldiers (or the ones that were assigned to us) really weren't all that great. I can't believe that any combat officer would go along with arming untrained, reluctant civilians as a means to augment his forces. Sounds like one of those "drying a poodle in the microwave" tales to me.
