Main battle tanks and legacy armored vehicles remain vital tools for mobility, fire support, and escalation management in Southeast Asia, despite the proven vulnerability of armor against modern drones and anti-tank guided missiles on global battlefields, according to an analysis published by eastasiaforum.org.
Cold War tanks remain active in Southeast Asia border disputes
Decades-old armored platforms continue to operate across Southeast Asia despite questions regarding their relevance in modern warfare. During border clashes in December 2025, Royal Thai Army M48A5 Patton tanks fought against Royal Cambodian Army T-55s. According to eastasiaforum.org, the use of these Cold War-era designs underscores the continued presence of legacy armor and the uneven nature of modernization in the region.
Global battlefields have seen drones, loitering munitions, and anti-tank guided missiles reduce the combat effectiveness of heavy armor. In Ukraine, cheap munitions have destroyed Russian armored columns since February 2022. Yet, the conflict also demonstrates that armored forces adapt by integrating new countermeasures, and Ukraine continues to receive main battle tanks and infantry fighting vehicles as military aid.
Diverse tank procurement drives regional military modernization
Military forces in Southeast Asia utilize a wide array of tank platforms obtained from Russia, China, and Europe. Data highlighted by seasiastats.com shows that this varied acquisition strategy reflects distinct defense partnerships across the region.
Indonesia operates the Leopard 2RI, a modernized variant of the German-made Leopard 2 series upgraded for archipelago defense with improved armor and battlefield electronics. Singapore fields the Leopard 2SG, featuring a 120mm smoothbore cannon and heavy armor. Meanwhile, Malaysia utilizes the PT-91 Pendekar, a Polish modernization of the Soviet T-72 platform designed to balance cost and combat capability, according to seasiastats.com.
Chinese and Russian influence remains prominent in other regional arsenals. Thailand operates the Chinese-built VT-4 main battle tank, while Myanmar fields the VT-1A and Cambodia retains the older Chinese T-59. Vietnam continues its long-standing defense relationship with Moscow by operating the Russian T-90, and Laos maintains Soviet-designed T-55 tanks.
Armored vehicles adapt to irregular conflict in Myanmar
Myanmar demonstrates how armored vehicles function within irregular civil conflict.
Thai Strykers and Pattons manage escalation at Cambodian border
The July 2025 border clashes between Thailand and Cambodia involved conventional militaries utilizing armor alongside mines, airpower, and artillery. Thailand deployed BTR-3E1s and M1126 Stryker infantry carrier vehicles assigned to the Royal Thai Army’s 112th Mechanized Infantry Regiment. eastasiaforum.org reported that Thai armor helped secure contested objectives and maintained perimeters against Cambodian forces equipped with ageing T-55s and BMP-1s.
The fighting caused major damage to the Preah Vihear temple complex, a UNESCO World Heritage site, and the adjacent Khao Phra Wihan National Park. Thai armor provided strategic and symbolic pressure, acting as a force multiplier and managing escalation through a visible show of force.
Did you know? Singapore maintains a heavily mechanized force despite its small geographic size, fielding indigenous infantry fighting vehicles and utility vehicles designed specifically for the nation’s operational requirements.
Frequently asked questions about Southeast Asian armor
Why do Southeast Asian militaries continue using Cold War tanks?
Regional militaries employ legacy platforms like the T-55 and M48A5 Patton because armored vehicles provide essential tactical mobility, fire support, and protected transport in limited conflicts and difficult terrain, rather than for massed tank battles.
What advanced Western tanks are operated in Southeast Asia?
Indonesia operates the modernized German-designed Leopard 2RI, and Singapore deploys the Leopard 2SG. Both variants feature heavy armor, advanced targeting systems, and 120mm smoothbore cannons.
How did Thai forces utilize the Stryker infantry carrier vehicles?
In July 2025, Thailand deployed newly acquired M1126 Strykers from the 112th Mechanized Infantry Regiment to the border. These vehicles secured lines of communication, maintained perimeters, and provided strategic pressure against Cambodian forces.
