- Most survivable Western tank with DU armor and blowout panels
- 120mm gun with M829A4 defeats all known armor
- SEPv3 adds improved electronics, power generation, and networking
- Interoperable with U.S. forces — shared logistics and ammunition
- Extremely heavy (73+ tonnes); limits bridging and strategic lift options
- Gas turbine is fuel-hungry; logistics burden in Australia vast territory
- Thermal signature is high due to turbine exhaust
- Strategic mobility to northern approaches is challenging
