Criminologist Professor David Wilson said prison guards likely enacted Operation Tornado to bring the latest riot under control.
It is a proven method using specialist officers that has been used many times before, he said.
"These are very well-tested systems and so it will be about trying to bring order back to HMP Maidstone. In these situations it's usually a question of being some particular incident that ignites the prisoners who want to take this kind of action and sometimes that action gets out of control."
