For 20 years, Defense & Security has been an important biennial as ASEAN’s Leading Tri-Service defence and internal security event, in Bangkok, Thailand. When Defense staged its first Tri-Service for Land, Sea, and Air in Bangkok in 2003 not many countries or international manufacturers paid much attention. The addition of the Internal Security section was added to the profile in 2007 and the event was soon on a path to become one of the region’s most important and dynamic exhibitions and could no longer be ignored.
