General ADF Knowledge and Skills

Operation POSTERN was a joint forcible entry operation in New Guinea, 1943, spearheaded by land forces from the Australian I Corps. It was a truly joint and combined operation that involved all three services and forces from Australia and the United States. A retrospective glance at POSTERN affords valuable insights for future maritime campaigning. For the foreseeable future, the core military problem for amphibious and littoral operational planners is likely to remain gaining access to maritime terrain across multiple contested domains, and generating sufficient combat power ashore to stage at or seize advance bases. Operation POSTERN offers important operational lessons in theater-shaping, deception, manoeuvre, and advance basing.

The 16th and 17th century was a period of significant change in the character of war. The drivers accounting for these changes were not all based in military reforms, despite Western Europe being engaged almost continuously in war. While tactical applications is interesting, it was the beginnings of some profound changes in the development of warfare; the professional military, the standing army, scale of warfare and subsequent emergence of the state (Crown) owning the monopoly on violence and the arrival of proper naval forces.

As technological advances increasing automate the control of weapons, it is timely to review the skills we need in our warfare professionals. Their core skills will increasingly be maintaining SA and making decisions in confusing and evolving circumstances. We need to ensure the ‘science’ and ‘art’ of warfare are balanced.
