SASless,
I am a Brit light blue (RAF) chap. Generally i enjoy the RAF/RN/Army banter in aviation. One thing I would NEVER EVER EVER criticize is the Brit army tactics/capability in land warfare especially counter terrorism/insurgency. The historical record speaks for itself.
So although, i think that the Taleban may try something on because uncle Sam has left, I have EVERY faith in those people I have worked with/ argued against in the British Army (I only argued with them on aviation matters). They know what they are doing.
To the army:
Go get em. Don't let the PC Media get in the way. No compromise.
