Thanks for the more useful reply. I must admit infanteer's post surprised me a little bit. I was researching online, which is what led me to this forum. And as a member of many other similar forums, it's been my experience that this should be the place to ask specific questions such as uniform details, since this is where the subject matter experts tend to hang out. Frankly, it was a pretty cold reception for a new member and it's the sort of thing that turns people away from taking a greater interest in Canadian military history. Not a great start.
I suppose I should have put the question in context - I have some knowledge of the period in question. To correct a few things written below, CF integration begins in the fall of 1964, with army HQ officially being stood down by the last CGS, Geoffrey Walsh on 31 August. It goes through a period of evolution, and CF unification comes into effect with the passing of Bill C-243 (the Canadian Forces Reorganization Act) in February 1968.
Mobile Command in fact was not entirely a land element. When it was officially activated on 19 October 1965 it included air staff in its command structure as well as air units under command. For eg., LGen Allard's original deputy commander designate and later deputy commander operational support was AVM Frank Carpenter. Each combat group in Mobile Command had its own tactical air support, provided by No.10 Tactical Air Group. Mobile Command evolved into FMC not as a result of a need to define the army element of the CAF, but because of a political desire to make the tile more bilingual - force mobile - mobile command - FMC. All of this information is easily found in the formation's annual historical reports among other primary sources.
I had looked at various photos of members in the CF tunic in Sentinel, DND's own Defence annual reports, etc., and for the period in question there doesn't appear to be a standard other than minimalism. Some soldiers are wearing collar dogs, others are not. I haven't seen anyone with a AMF(L) fob and have seen both cloth and metal wings. Wasn't sure about command badges - I don't know when the mobile command pocket badge came into use.
Anyway, thanks for the replies. If I discover anything further in my own research elsewhere I'll leave a post here for those interested.
