Like lets say hypothetically that 100 Sardaukar fighters armed with their bladed weapons and personal shields were to go against 200 Krieg grenadiers with full entrenching gear, melta bombs, krak grenades, heavy stubbers (because its an easy win for Krieg if they had lasguns since lasers make Dune shields into mini nukes), gas grenades, and bayonets.
Both sides fight in the ruins of ww2 Stalingrad, which elite bloodthirsty fighting force gets owned?
Off topic, but a fun little sideplot in Children of Dune is that the Sadaukar were so blown out by the Fremen that they undergo an identity crisis.
