The M113 armoured personnel carrier has been operated by the Australian Army in large numbers since 1964. Either 817 or 840 M113s were acquired between 1964 and 1979, comprising nine different variants. In Australian service, the M113 has equipped armoured transport and reconnaissance units as well as mechanised infantry formations. It has been used as a support vehicle by many other units. The type played an important role in Australia's commitment to the Vietnam War between 1965 and 1972 (pictured). Small numbers of M113s were deployed to Somalia during 1993 and Rwanda between 1994 and 1995. Larger numbers of M113s operated in East Timor from 1999 to 2002 and 2006 to 2008. A long-running modernisation resulted in 431 being upgraded between 2007 and 2012. Despite the upgrade program, the Australian Army's M113s are now obsolete and they have not been included in recent deployments due to their vulnerability. Replacement infantry fighting vehicles are scheduled to enter service from 2025. (Full article...)
