The proposed unit follows controversial plans for a single access point to the Internet, dubbed by online protesters as the "Great Firewall of Thailand" - in reference to China's draconian web surveillance - because it would make it easier to monitor the web.
While Thai premier Prayut Chan-O-Cha has insisted no conclusions have been reached on the single gateway, the issue has mobilised campaigners.
Today defence minister Prawit Wongsuwon told reporters the military is planning to form a new unit to counter online dissent.
The announcement comes at a time the regime has expressed mounting concerns over perceived royal defamation with prosecutions skyrocketing since the May 2014 military takeover.
Earlier today the "Citizens Against Single Gateway: Thailand Internet Firewall" vowed to launch unspecified attacks against the junta if the gateway plans were not cancelled.
"In order to win the cyber war this time, we must use brains, skills and patience," said the group in a Facebook post.
Authorities responded by saying they would trace and arrest future attackers.
A spokesman for the group told AFP that it had "trained several hundred people" for cyber attacks.
"We're training them in how to prevent being traced by the government," the spokesman said in an email.
Thailand's monarchy is protected by one of the world's strictest lese majeste laws with most new cases brought over perceived insults online.
In a record-breaking August conviction a man was sentenced to 30-years over the content of six Facebook posts.
