a further 16 rounds stowed in the additional stowage place - the conveyer
located in the hull, and two more rounds are stored in the fighting compartment.
Types of ammunition that can be fired by the gun include rounds of all types and
purposes developed in compliance with NATO standards - STANAG 4385 and STANAG
