Mr Point, nice thought and a great job for the Flt Ops branch.
Start with a large, basic global political chart and red pen. Cross out all those countries neutral friendly to Opfor. Take an orange pen and cross out all those countries not friendly to us.
Take a ruler and blue pen and draw in tracks from MOD to potential FOB via staging posts. Measure distances. Use kilometers then no one will have the wrong type of miles.
Problem with Nairobi, from a bomb truck or interceptor POV is that it is 1000 miles the wrong side of the action.
Kampala is better but still the wrong side.
Egypt is about the same distance from the action but closer to home.
Now Chad is a bit far from home but closer to the action and the wrong side from the POV of Opfor. It will also have a decided advantage in more than adequate stocks of Vin Rouge
