Basic Military 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.

All combat operations need real-time, concrete intelligence, but the counterinsurgency operations’ (COINOPS) margin of error runs thinnest. In their fast, multidimensional context, COINOPS demand more comprehensive intelligence at platoon/company levels than conventional warfare does. This article explores the need for tactical unit leaders fighting insurgencies to have more intelligence assets available in the field in order to offer swift analyses to aid decision making in highly fluid environments.
