The knowledge that the terrorists have the weapon has already changed the way the French are carrying out their five-month-old offensive in Mali. They are using more fighter jets rather than helicopters to fly above its range of 1.4 miles (2.3 kilometres) from the ground, even though that makes it harder to attack the jihadists. They are also making cargo planes land and take off more steeply to limit how long they are exposed, in line with similar practices in Iraq after an SA-14 hit the wing of a DHL cargo plane in 2003.
