I feel sure you appreciate it was ever thus OA......right back to the 1960s it goes..when the total UK size of the tri-service SH fleet was "capped" at Brigade lift capacity.......never made it in those days particularly after the first UK CH47 buy was canned....but at least we have got a lot closer now. Its concurrent high tempo ops that screw us of course ......particularly when helo lift becomes so essential all the time tomnimise casualties- asymetric warfare was not thought of in those far off days......we never learn do we?
