Critics observed that Thai military's main objective is to deal with internal rather than external threats. Internal Security Operations Command is called the political arm of the Thai military, which has overlapping social and political functions with civilian bureaucracy. It also has anti-democracy mission. The military is also notorious for numerous corruption incidents, such as accusation of human trafficking, and nepotism in promotion of high-ranking officers. The military is deeply entrenched in politics. Most recently, the appointed senators include more than 100 active and retired military.
