This is also what I was thinking to make a difference with the usual US Icons Identification, (when we are using only the british force of course), a real british situation and not the "NATO model" like the US ones, a little like the OKW German Icons, a touch of reallity !
(Canadian Cat Icons) are the most close to the reality to representing the ww2 Icons, including Icons for CMRT, but...this is only MY opinion, correct me if I m wrong !
