They are literally describing the 1998 film Solider. I swear these fkers saw that movie, have probably watched it 50 times and rather than thinking it's a cautionary tale about the US direction toward militarism instead took it as a guidebook.

Movie is worth a watch if you haven't seen it. Has the trainers raising the children like chattel. When one of the 10 year old kids can't keep up during a run, the trainer has him stop then puts him down like a lame race horse. The other children hearing the gunshot after they are out of sight is motivation or something. The main character has flashbacks to various campaigns he fought in and honestly they are battlefields the US military is already foaming at the mouth to start wars on. Scenes like slaughtering Chinese settlements on the moon and planting American flags kinda stuff.

Don't bother with the squeal, it's trash like most from that era and the first movie was only okay not great. The sequel is all about the wholesome eugenics breading program soliders being morally better than the genetically engineered test tube baby soliders. American brained morality.
