Lt. Gen. Donald M. Gumiran, Commanding General of the Philippine Army, took the stage as a panelist at the Australian Army's Chief of Army Symposium (CAS) 2026 on October 8, 2026, held at the Perth Convention and Exhibition Centre in Western Australia — outlining how the Philippine Army has institutionalized military adaptation across its doctrine and force design.
Theme and Four Guiding Principles
The symposium was held under the theme "Hardwired for Adaptation." The Philippine Army's Office of the International Military Affairs (OIMA, PA) said Lt. Gen. Gumiran structured his presentation around four core principles that define the Philippine Army's approach to adaptation.
The first principle, according to OIMA, PA, is that adaptation must start with the ability to unlearn. Lt. Gen. Gumiran noted that the Armed Forces of the Philippines tests concepts across both internal security operations (ISO) and external security operations (ESO), which requires troops and institutions to set aside outdated doctrine when situations call for it.
The second principle describes how adaptation travels from the tactical level up to institutional structures. As a concrete example, Lt. Gen. Gumiran pointed to the government's response during the 2017 Siege of Marawi, explaining how combat lessons from that campaign were absorbed into the army's broader institutional framework.
Force Design for an Archipelago and Exercises as Learning Tools
The third principle, as reported by OIMA, PA, deals with force design — which Lt. Gen. Gumiran argued must remain adaptive rather than fixed, especially given the Philippines' character as an archipelagic nation. This involves integrating unmanned systems, developing counter-drone capabilities, and reshaping combined arms training to allow for continuous evolution even under resource limitations.
The fourth principle reframes military exercises not as performance showcases but as genuine laboratories for learning. Lt. Gen. Gumiran stressed that exercises should deliberately expose troops to failure and difficulty in order to build authentic adaptive capacity, rather than reinforcing confirmation bias.
Whole-of-Nation Approach and Defence Partnerships
Lt. Gen. Gumiran also addressed the Philippine Army's broader role in the country's whole-of-nation approach to development and peace, according to OIMA, PA. He referenced the policy environment shaped by civilian leaders on counterinsurgency, as well as the implementation of agreements with international defence partners.
The Philippine Army said its participation in the symposium reflects its role in advancing national and regional security, and that experience gained through both internal and external security operations offers a practical framework that partner nations may draw from.
Senior Indo-Pacific Military Leaders on the Panel
The CAS 2026 brought together senior army commanders from across the Indo-Pacific region. Joining Lt. Gen. Gumiran on the panel were Chief of Singapore Army Maj. Gen. Cai Dexian and New Zealand Army Deputy Chief Brig. Hamish Gibbons. Australian Army Deputy Chief Maj. Gen. Chris Smith served as the panel moderator.
The symposium was held as part of the Land Forces 2026 International Land Defence Exposition, a three-day event that ran from October 6 to 8 at the same Perth venue.
By the Numbers
- 4 — principles of military adaptation presented by Lt. Gen. Gumiran at CAS 2026
- 2017 — year of the Siege of Marawi, cited by Lt. Gen. Gumiran as a case study for institutional learning
- 3 — total days of the Land Forces 2026 exposition (October 6–8, 2026)
- 3 — other senior army leaders on the panel representing Singapore, New Zealand, and Australia
Why This Matters
The Philippine Army's role as a panelist — rather than simply an observer — at a major multilateral defence forum signals growing recognition of the institution's operational experience among Indo-Pacific partners, according to the Philippine Army. Lt. Gen. Gumiran's presentation drew directly on the Siege of Marawi and ongoing security operations, framing Philippine doctrine as a practical reference for allied armies. The Philippine Army also stated that the engagement reinforces its defence relationships with Australia, Singapore, and New Zealand amid evolving regional security conditions.
