Wonderful - Apache sweeps in to its forward base, lands between two pairs of grunts, one leaps forward and spears it with the refuelling nozzle, the others clip more rockets on, and 6.8 seconds later it's on its way back to the front line.
Most of the time.
Occasionally, the refueller pulls out the probe, big splash because it's gone wrong, wumph! and a dozen others rush over with fire extinguishers. Location of forward base no longer a secret as there's a 200ft column of black smoke pointing to it. Or, 6.8 seconds are up, off goes the heli with a crew of three - yep, the refueller didn't manage to get the probe out. How much is Bernie Ecclestone paying them to take this?
