The SASR was generated in the chaos and fighting of World War 2. An answer to the British army's new special forces regiment that put down more than 300 German fighters in several months. A united commonwealth between the UK and Australia saw the Austrailian's believe that they should have their own SAS and thus, the SASR became perhaps, the son of the first special forces unit in warfare to ever be created. Although differing in many ways, the SASR has some similarities, some of the information passed down from the SAS to the SASR provided the with their own adaption of SERE, a ruthless and brutal training course designed to pick the 10 men from 100 who can bear the physical and mental side of special forces capability. The SASR has existed for a many few more years longer than MARSOC and has seen several more deployments from today's Afghanistan to the ruthless and brutal jungles of Vietnam where the SAS went head on with the Viet Cong and the NVA, the SASR bring extensive resembalance to the SAS which has defeated step ups from MARSOC like the SEALs. The SASR have more experience, more years on the field in which they have fought more battles, learnt more lessons and has developed from the special forces unit, the SAS. Overall, the SASR will crush MARSOC with a longer operating experience and deeper more challenging training.

Edge: SASR

P.S. - Get your details right, the SASR don't use the SASKWTLN, they use this bad boy.
