Army doctrine specifies that the role of commando units is to "span the gap between conventional infantry operations and unconventional operations", focusing on advanced force operations and direct action missions. The role of the regiment is to conduct large scale offensive, support and recovery operations beyond the scope and capability of other Australian Defence Force (ADF) units. Part of Special Operations Command (SOCOMD), the 2nd Commando Regiment is one of three combat-capable units within SOCOMD and operates in conjunction with other SOCOMD units, services and interagency organisations in joint and combined operations.

It has also been involved in domestic security operations including the 2006 Commonwealth Games and the 2014 G20 Leaders Summit. The 2nd Commando Regiment often trains and deploys with the Special Air Service Regiment, is highly regarded by coalition special operation forces abroad, and has been involved in operations in East Timor, Iraq and Afghanistan, where it was used in a direct action warfighting role. It is based at Holsworthy, New South Wales. The regiment was established on 19 June 2009 when the 4th Battalion, Royal Australian Regiment (Commando) was renamed.

The 2nd Commando Regiment is a special forces unit of the Australian Army, and is part of Special Operations Command.
