This research project seeks to chart out the officer education for the militaries of key Asia Pacific countries. This report will provide a strong basis to compare and contrast the state of officer training and education between ASEAN members and other militaries in the region. The analysis from this report will provide a number of policy implications; a criterion for effective Professional Military Education (PME) across nations and services, a review of current officer training and education, differentiating how different Services approach officer education, as well as offering insights on how bilateral and multilateral relationships could be further enhanced through defence diplomacy.
