There must be some limitation with using UAVs for ISR tasks (perhaps someone who knows a bit more will explain why), hence why the UK is shifting to a manned platform like the DA42 as well as continued use of Reapers, etc. The US is also looking to boost its manned ISR capabilities for Afghanistan and Iraq at the moment (requirement for 21 aircraft) with reports suggesting that aircraft like the Seabird SB7L-360 Seeker (as already operated by the Iraqi Air Force) and the Schweizer RU-38 are possible in addition to buying 30 C-12 aircraft.
