The following is a South Korean training video. It shows some remarkable infantry tactics, a kind of update of ancient infantry tactics. South Korean protests get rather unruly, as the video may suggest.
Note the flanking maneuver from 2:33-3:20 or so, where a wing of the enemy is cut off and destroyed (presumably in this case, they would merely be arrested). Also the use of a kind of pure-infantry bounding overwatch from 5:30-7:00. This allows them to advance against significant resistance, including incendiaries, and capture territory while maintaining formation.
