It features a new engine/transmission/transfer case, new suspension, new tracks, roadwheels, drive sprockets, an up-armoured hull (armoured against 14.5mm armour piercing ammunition), an air conditioning system, a new electrical driven turret incorporating a computerised fire control and integrated day/night optical sights, a "new" 0.50Cal QCB (quick change barrel) HMG, in addition the infantry carriers will be stretched by 75cms, to allow 10 troops to be carried "comfortably". These vehicles when in service will probably be fitted with a flex mounted MAG 58 7.62mm machine gun, to improve the vehicles somewhat limited firepower...
