Will the Elefant crew have different uniforms?

From what I can find, both Heer and SS tank destroyer crews wore field grey uniforms, rather than the black worn by the tank crews. Will the Elefant’s crew in CaP have field grey?

On a related note: Will the crews of the Su-122 and Su-152 sport the right insignia, indicating them as artillery troops?
