Winter training is rare, and summer training is true and false. Generally, it is 140 in summer and 180 in winter.

Summer collar and epaulettes 1 1 small suit collar and epaulettes.

Winter works are all epaulettes, but under 1 1, a small suit collar seems to be different from the new camouflage green one, and the color is similar to that of wj coat in cold areas. This is what I know (WJ retired at the end of 1 1).
