   The M113AS4 is an Australian upgrade of the American M113A1 armored personnel carrier, which was introduced in the mid-1960s. Currently Australian Army operates about 700 ageing M113A1s. These are used in armored reconnaissance and armored personnel carrier roles. A total of 431 M113A1s will be upgraded to M113AS3 or M113AS4 standard under the LAND 106 program, allowing active service until at least 2020. First initial production vehicles were delivered in 2007.

  Upgrade involves fitting new engine, transmission and drivetrain. The M113AS4 is lengthened to fit an additional pair of road wheels and has improved carrying capacity. Upgrade also provides enhancement in firepower. The M113AS4 is fitted with a new one-man turret, armed with a heavy machine gun. It is worth mentioning, that Australian Army uses armored personnel carriers for light infantry fire support.

   Protection of the upgraded APC was enhanced by add-on ceramic armor tiles. Hull was reinforced for additional protection against landmines and IED blasts. Interior was fitted with spall liner. Vehicle's hull provides protection against up to 14.5-mm rounds.

   Interior of the stretched APC was also improved, as well as habitability for the passengers. Troops enter and leave the vehicle via the rear ramp or roof hatches. Ramp is completed with emergency exit doors.

   This armored personnel carrier is powered by an MTU 6V199TE turbocharged diesel engine, developing 350 hp. This armored vehicle is fully airportable.
