Mixed troop and direct fire assault, dual level carriage. Although this car has one less gun station compared to the command variant, it can provide an increase in direct fire for overlapping arcs of fire through the split level arrangement - top gun position can fire over the top of the lower.
For a direct fire assault, two tank guns can be mounted with a half platoon of infantry within the troop section.
For a mixed car, an assault gun on the upper deck and anti aircraft gun on the lower, an optimisation of direct fire support and organic air protection can be achieved. If infantry assault the train, the anti-aircraft machine guns can also be lowered to rake fire through the troops.
