The Group Gerak Khas (Special Service Group) is a special forces regiment of the Malaysian Army which conducts special operations missions for the Malaysian government, such as direct action, unconventional warfare, sabotage, counter-terrorism, and intelligence gathering. It is the administrative and operational group to which the three regiments of the Rejimen Gerak Khas and its supporting units are subordinated.

While the GGK traces its origins to 1965 and the post Indonesia-Malaysia confrontation, they gained fame and recognition worldwide after successfully assaulting the communist terrorist in the jungle during the Communist Insurgency War.

21 Gerup Gerak Khas is commanded by a Brigadier General and is currently located at Iskandar Camp, in Mersing, Johor comprising 11 Gerak Khas Regiment tasked to counter-terrorism, 21 Commando Regiment and 22 Commando Regiment. The three regiments' tasks are guerrilla/anti-guerrilla warfare, escape and evasion, subversion, sabotage, counter terrorism, asymmetric warfare and their most highly regarded expertise – jungle warfare.
