All the recce kit in the GR4A was disabled several years ago, making it essentially identical to a GR4, just without a gun. Both types would either use a Litening or RAPTOR pod to do visual or IR imagery. Especially with a RAPTOR pod, vast areas of imagery could be hoovered up very quickly; it's the painstaking analysis that takes the real effort and time.
RAPTOR was used in the Raoul Moat search, and has been said, the search for a campsite made it a somewhat different task than that currently being discussed.
Edited to add: sturb199 beat me to it - well almost - it's not just old hat, it's gone!
