Chateau Ver de Fleur is quite correct in his testimony that the GR7a is providing more than its weight in gold. If memory serves the boys are providing something like 10% of current OEF CAS as well as providing a pair on GCAS for circa 10 hours per day.
The only thing the GR7a is lacking is a gun and an advanced targetting pod such LITENING or SNIPER. Combine these with ROVER III terminals for the JTAC on the ground and boy you'd have one hell of a great CAS platform.
Oh SASLess, better get your fact right about the state of Kandahar's runway before posting outdated, misinformed info.........................
