The basic concept was to raise and train a reconnaissance and surveillance unit that would take over the SASR's tasks in northern Australia. Because the RFSUs receive SASR training support, the small unit tactics of the two units are similar and there are regular personnel exchanges - especially with regard to SASR personnel being posted to RFSU to keep the SASR 'up to speed' with the skills required to train indigenous peoples in guerilla warfare. However, the RFSU also are commanded and staffed by Royal Australian Regiment personnel. The command concepts, training continuum and even the capacity of the RFSU to focus on the generation of sustained and widespread operations in remote Australia differentiates the RFSU distinctly from the SASR.
