Thailand has always offered military roles to Thai women, some 54.55% of women represent the National Human Right Commission and 10% of the National Reconciliation Commission. Thai women have been empowered to serve in the military, assigned roles as negotiators, mediators, and facilitators, as well as involvement in security operations. However, they still remain excluded from playing active roles in armed conflict.
