I apologise because I know this subject was raised sometime before but.. I thought that the AMS was being rather grown up and declining to join in with this rather juvenile military fashion of TRF badges, but today I saw the new RAMC and QARANC TRF's Oh dear! Can anybody tell me what the TRFs are for? I can understand the tactical usefulness of being able to recognise other members of yuor battlegroup - ie the airborn DZ patch, but what is the tactical reason for recognising what regiment or corps a soldier is in. In fact that could lead to confusion - a cook (RLC) serving with an infantry battlegroup might be mistaken for a trucky (RLC) in an LSR. Or an Evironmental Health Officer (RAMC) might be mistaken for a Doctor. How does it help me, tactically, if I can identify that a soldier belongs to one of the 7 battallions of the Royal regiment of Scotland - and he may not be serving with one of the 7 Scottish battlegroups. And how does it help, tactically, to be able to identify the RAF?
