Officers did use EM tunics during the war. If you look at the M36 uniform , the officers have several noticable differences :-
1 Generally 6 buttons instead of 5
2 No belt hook holes around the waist
3 Turn back cuffs
4 Higher collar held together with 2 clips instead of 1
5 Generally better quality wool , or often garberdine
6 Proper silk lining
7 Patch pockets have more pronounced points to the flaps .
How do I know all this ?, I''ve just paid ot have one tailored to replace my EM one 
Far East - the blokes not on Ebay anymore . 
What rank are you doing ?
Yes it was some guy ..... well this Guy who was on about it . Pirschen1975 on ebay . Jacket came one day after i needed it 
Not at all bad for the price. The wool is much finer and the jacket lighter than the Sturm EM one I've got , and it fit's a lot better apart from the neck which he's made too small .I'm hoping a bit of wearing /slimming will resolve this issue.
