The ADF does not even have the airlift capability to sustain the current deployment, let alone adding tanks. Thats why contractors are often used. One subject I do know is ADF logistics. The sheer amount of man-hours and parts required to support armoured vehicles (particularly tanks) in the field is astounding. I am not saying we can't do it, but it would take a lot more logistical support to sustain them. It is not just a matter of moving the vehicles.
