Here is the Russian Infantry Insignia set of WW2.  They must be cut from the sheet and glued to the uniform with either white glue or fabric tack. Whit glue is good if you want to reuse the tunic you can soak it in water and remove the insignia. Any thing you don't see, I probably have, so just ask. I have a large selection of cuff title and armbands. If you don't see what you need, let me know. Postage will be by standard first class letter post.
