The Combat Police are deployed at demonstrations and rallies where violent disorder may occur. When such an event becomes violent, they rush in and contain the protestors with long batons and metal shields. When blocking the passage of illegal protesters, the Combat Police use the "passive formation", where the shields are held up to make a small wall. This is the most frequent formation used. However they are also trained to retaliate against protestor attacks by angling the shield and pushing, or by jabbing the shield at protestors in this formation.
