Panzerschreck in Worldwar
The Panzerschreck was introduced to the German infantry in their war against the Race. It wasn't powerful enough to penetrate the armour of Landcruisers, but was more than effective against Troopcarriers. Landcruiser crews ended up with a particular hatred for Germans who used this weapon.
