The under lying mod- ernisation initiative is referred to as Proj ect LAND 400, which, along with training and integration capabilities, largely consists of replacing key combat vehicles, including the Australian Light Armoured Vehicle (ASLAV) and the M113AS4 armoured personnel carrier (APC) with an infantry fighting vehicle (IFV).1 Proj ect LAND 400 involves planning over a relatively long time horizon and by intent is shaping forces through a relatively low- risk approach that will, within this context, maximise combat effectiveness.2 To assist with this decision, the Defence Science and Technology (DST) Group asked the RAND Corporation for help in assessing the range of trade- offs between tracked and wheeled combat vehicle classes. This request entailed completing three tasks. The first task involved assessing lessons learned about tracked and wheeled combat vehicles in recent conflict in vari ous parts of the world; the second task involved assessing the implications of advanced technologies on the vehicle classes; 1 The workhere is focused on Phase 3 of the Proj ect LAND 400 initiative. Phase 1 of the initiative was largely a scoping activity; Phase 2 is focused on a follow-on mounted combat reconnaissance capability, largely defined by a combat reconnaissance vehicle (CRV) replace- ment to the ASLAV; and Phase 3 is focused on a follow-on mounted close combat capability, largely defined by an IFV replacement to the M113AS4. 2 An industry pre sen ta tion given by BRIG Greg McGlone, Director General, Combined Arms Fighting System, on November 27, 2015, indicates an interest in “minimising develop- mental risk” using “mature technologies with a growth path.” iii iv Assessing Vehicles for Australian Mounted Close Combat Operations and the third task involved examining system- level implications of the differ ent classes of vehicles. This work should be of interest to Australian defence policymak- ers and planners, especially those directly affiliated with the Proj ect LAND 400 initiative. U.S. policymakers and planners and other mem- bers of the American, British, Canadian, and Australian (ABCA) armies may find this work of interest, because it identifies the trade- off space that one of the core member allies of this group faces in its effort to modernise its mechanised forces, and it may offer ideas with re spect to future integration and collaboration among the larger group of allies.
