The dense vegetation and rough ground in the theater took a surprisingly heavy toll on the fuel consumption of the brigade's vehicles. Diesel usage rates for cross-country movement proved much higher than expected for off-road travel. Keeping the several hundred SADF vehicles full of gas was a constant worry; at times the columns had to be withdrawn from combat prematurely or redistribute gasoline within the battle groups to
reach the refueling points. Fuel moved by air and ground to Mavinga, from there tanker trucks shuttled back and forth to the front. On previous external operations SADF mobile columns often resupplied their helicopters with fuel; the tanks of the Ratels and supply lorries provided a sort of mobile FARP for the aviation element. During Modular helo operations were limited by the air threat to night time casualty evacuation, so ground based fuel for wide ranging C2, air assault, and fire support helicopters wasn't necessary.
The US would have handled the logistics of this with a breeze (in my opinion).

One needs to look towards the competence of the staff officers and logistics units before reading too much into all this.
