question
in GWI RAF/AAC borrowed M4 Mk X IFF from the Americans, and handed it back after the war
the question is, did they borrow the (NATO standard!) kit agian this time or has the UK MOD installed it by now?
keep in mind, for a ground base air defence operator it is way worse than to let slip a valid (high speed, jamming, negative IFF, non ACO) target trough than to kill a vital target in weapons free / TBM automatic that in this case sadly turned out to be a friendly
hope GWII will be short and decisive, good luck to every one out there
