Is the UAV really as important as what it was shown to be? I sometime think that the UAV is overrated. It is useful in difficult terrain and against a troop that are technologically inferior to yourself and had no means or very limited means of shooting it down from sky. However against a force that is almost the same as yourself and/or have plenty of means of shooting the UAV down, then the UAV is only flying target boards.
I think that the main reason why the Russian are not using their UAV is not just because their troops are not really train much with the UAV but basically because it was useless against the Georgians who are trained and equipped by the US and I believe had enough Manpads and AAA to easily bring down the UAV easily.
Plus no matter how cheap a UAV is, it still cost quite a heafy sum and to waste them in operations so quickly is really not a very clever thing to do.
