Initial plans were for the SAS to carry out their traditional raiding role behind the Iraqi lines, and operate ahead of the allied invasion, disrupting lines of communications. The SAS operated from Al Jawf, on 17 January, 128 members of A and D squadron moved to the frontline there they inserted three road-watch teams into western Iraq to establish observation of the MSR traffic on 18 January 1991, the first eight SCUD-B ballistic missiles with conventional explosive warheads fell on Tel Aviv and Haifa, Israel, it was this attempt to bring Israel into the war to undermine the coalition by shattering the coalition of Arab nations arrayed against Iraq, that was directly responsible for a dramatic increase in operations for the Regiment. On that day they were tasked with hunting Scuds. An operational area, known as "SCUD Box," covered a huge swathe of western Iraq south of main Highway 10 MSR, was allocated to the SAS and nicknamed "SCUD Alley", Delta Force deployed north of Highway 10 in "SCUD Boulevard," two flights of USAF F-15Es on "SCUD Watch" would be their main air support component. Both SAS and Delta operations were initially hampered by delays in bringing strike aircraft onto the often time sensitive targets-a problem only partially alleviated by the placing of special forces liaisons with the US Air Force in Riyadh, Saudi Arabia. On 20 January, they were working behind Iraqi lines hunting for Scud missile launchers in the area south of the Amman — Baghdad highway. The patrols working on foot and in landrovers would at times carry out their own attacks, with MILAN missiles on Scud launchers and also set up ambushes for Iraqi convoys,
