I wonder if they mean Army Lynx as the RAF don't operate Lynx. If the Army Lynx replacement is vulnerable, what about the Royal Navy Lynx(?) or is the Army and RN Lynx one and the same?
As I understand it they are very much dependant on each other financially so to cut one will mean you cut both variants.
As for differences, RN one has additional Radar and FASGW capability along with only one ste of controls whereas the Green version will have no Radar, no FASGW and a set of duals.
