To FAPLA, the experience of planning and executing an operation of such massive proportions was relatively new, but the Soviet military mission was convinced that a decade of exhaustive training on its part had created an army capable of undertaking a complex multi-divisional offensive. The Angolan brigade commanders had repeatedly expressed reservations about splitting the force and fighting on two fronts, arguing that a single assault on Mavinga would be more linear and sufficient. FAPLA's Cuban advisers objected on the grounds that South Africa might intervene on behalf of its erstwhile ally. "Don't get into such wasting, costly, and finally pointless offensives," Castro had vented to Gusev's staff. "And count us out if you do." General Arnaldo Ochoa, the senior Cuban military officer in Angola, also protested that the tactics FAPLA were being forced to adopt were more applicable to combat operations in central Europe than an offensive against an irregular fighting force on the broken African terrain. Ronnie Kasrils, MK's intelligence chief, warned the Soviet mission that if Saluting October proceeded an SADF counteroffensive was imminent. Gusev overruled the Cuban and MK concerns, and the operation commenced without contingency plans for a South African intervention.
