Kettenkarres are equipped with fixed-mount MG71 machine guns fired
by their drivers with an electrical trigger. They spearhead Prussian
assaults and act as a physical barrier if necessary to shield the
Grenadiers from enemy fire, while using their own formidable
weaponry to suppress target positions. Once the combined formations
are within range, the infantry break cover from behind the Kettenkarres
and storm forward to overwhelm the enemy defenders, with the
tankettes offering supporting fire.
