These would be for the 1st Canadian Armoured Brigade: Ontario Regiment, Three Rivers Regiment, Calgary Regiment This type would be useful for Corp and Divisional RSASC units, as they did not have the white bar at the bottom I have seen both used, with white or red bar, but I believe you are correct in that most used the red bar. The sheet could be used with corps and divisional by removing the white bars. The sheets are very useful, just require a little research as to the correct applications. Most of the AOS have never been produced before, thus it is great to now have them.

Not following you here - are you saying the red over blue ones are for 1 CAT Bde? Some of the AOS numbers jive with 1 Cdn Army, ie 174 is 191 Fd Regt RA, and 175 is 5 Med Regt RCA. I just used RCASC as an example. The fact is the all the Corp AOS markings *should* have a white bar at the top, and *none* of the AOS markings have this white bar, therefore they shouldn't be paired up with any of the 1 or 2 Corps Formation signs. Also, from what I can see 1944 an onwards, all the Divisional RCASC AOS markings (ie ones with no white bar on top or bottom) were two digits. The ones on the sheet are all 3 digits. Exception being 82, which has a 1 st Cdn Army white bar on the bottom, the only 2-digit RCASC AOS marking I've seen for 1 Cdn Army was HQ, which had number 50. Though they might be applicable for 1 CATB? Archer's web page states the sheets may have deliberate mistakes to prevent copyright violations... I hope that is what I'm seeing.

So................... a rather strange argument since these are sign used over 60 years ago! But is there some documentation where a non-Canadian can find a reliable explanation about how to use which sign where and in a right combination?

[/quote] The numbers match the tank brigade markings, but the red over blue s arty _only_. The 1 CATB markings are brown over blue. They are suitable for arty units in 1 Cdn AGRA. (For the Cdn army, of course.) Paul

Graeme You are correct, even Corps units would have the white bar. As I see the decals, the Blue over Red would be 1st CAB, and I believe the 3 digit RCASC, "176" would be the 1st CAB unit. 1st CAB kept there 3 digit AOS until the end of the war. Kevin

LOL, I'm colour dyslexic today! I saw blue over red, but my brain thought red over blue. Interesting that pretty much every type of AOS is represented on that sheet, except Artillery.

Hi Paul, I did this up around 10 years ago. Its for 1944 onwards for units of 1st Cdn Army. I would love to see someone do something similar for 1 CATB etc. Formation and Arm of Service Markings, 1st Canadian Army 1944

Hi Graeme, That realy helps non-Canadians to understand. Thanks a lot. P

Paul/Graeme Here is some images of org charts I did, that can be saved/printed for reference. They are not totally complete, and I will find time to finish them eventually.
