This present study aims to examine the representations of the Armed Forces of Myanmar in Thai news headlines as well as to unearth the ideologies of the news headline writers that are hidden in the headlines based on the Critical Discourse Analysis (CDA) approach. The data used in the analysis were headlines written in Thai which were gathered from a well-known and credible Thai local news website. These headlines were all related to the protests against the military coup d’état which took place in 2021 in Myanmar. The theoretical frameworks employed in the analysis of the collected headlines include the representational strategies (van Leeuwen, 1996) and the transitivity analysis (Machin and Mayr, 2012). In terms of the representational strategies, the results of the analysis showed that the Armed Forces of Myanmar were represented mainly using functionalization and collectivization. Each division in the army was represented by their roles and they were collectivized and viewed as groups because the headline writers did not refer to any particular individuals who were involved in the coup d’état and the violent suppressions of the protests. In addition, the results from the transitivity analysis showed that the Armed Forces of Myanmar were represented as actors or agents in the material process which involved a lot of violent action verbs such as kill, suppress, and shoot. The findings of the study clearly reflected the representations of the Armed Forces of Myanmar and also how news may construct the social identities of the Armed Forces of Myanmar among people.
