Meanwhile, A and D squadron mobile patrols were tracking down SCUDs and destroying them if possible, or vector-in strike aircraft. Both squadrons were equipped with six to eight Desert Patrol Vehicles (DPVs) in four mobile patrols/fighting columns. The mobile patrols used the "mothership" concept to resupply their mounted patrols, along with the DPVs, a number of cut-down Unimog and ACMAT VLRA trucks were infiltrated into the area of operations and served as mobile resupply points, themselves being stocked with fuel, ammunition and water by RAF Chinook drops, this meant that the SAS mobility patrols could effectively stay in the area of operations indefinitely. During one mission an operator reportedly destroyed a SCUD launcher with a vehicle-mounted Milan anti-tank guided missile. An Iraqi Army command-and-control site known as "Victor Two" was attacked by the SAS: SAS operators crept in to the facility and set a batch of demolition charges which were counting down to detonation when they were compromised, the SAS destroyed Iraqi bunkers with Milans and LAW rockets, operators engaging in hand-to-hand combat with Iraqi soldiers. The operators broke cover and braved enemy fire to reach their vehicles and escape before the demolition exploded. Another mounted patrol from D squadron was bedding down for the night in a desert wadi, later they discovered they were camped next to an Iraqi communications facility, they were quickly compromised by an Iraqi soldier walking to their position. A firefight erupted between the SAS and at least two regular Iraqi Army infantry platoons. The patrol managed to break contact after disabling two Iraqi technicals (pick-up trucks) that attempted to pursue them, during the chaos of the firefight a supply Unimog had been immobilised by enemy fire and left behind with no sign of the seven missing crew members. The seven SAS operators (one of whom was severely wounded) had captured a damaged Iraqi technical and drove toward the Saudi Arabian border, eventually the vehicle ground to a halt and the men were forced to travel on foot, after 5 days they reached the border.
