Special Forces Status
The Raiding Support Regiment (RSR) was regarded as a Special Forces unit during World War II.
They operated under the umbrella of "Raiding Forces" alongside other famous elite formations.
1. Origins as an SAS Offshoot
The regiment was originally formed in North Africa in 1943 as a direct offshoot of the Special Air Service (SAS). The personnel were entirely volunteers drawn from various Allied nationsprimarily British, South African, and Rhodesian troops.
2. Specialized Elite Training
Every member of the RSR underwent intense special forces training, which included:Parachute training for airborne insertions.Master proficiency in both Allied and Axis weaponry.
Specialized tactics in sabotage, mountain warfare, and amphibious operations.
3. Their Unique Special Forces Role
While units like the Special Boat Service (SBS) and the Long Range Desert Group (LRDG) conducted light stealth reconnaissance and hit-and-run raids, they lacked heavy firepower.
The RSR was specifically created to solve this problem.
Operating in small, highly mobile structures, they provided heavy weapon support (such as heavy machine guns, mortars, anti-tank weapons, and mountain howitzers) to local partisan and guerilla armies behind enemy lines in Yugoslavia, Albania, and Greece.
