I based this on my own uniform ;)

The smocks were actually quite green.

All enlisted men basically looked alike, though the number of gulls on your collar changed. As a nco, you gained silver trim on your Feldbluse and started wearing gulls on your jump smock. Otherwise, its really hard to tell the difference between the various ranks of FJ - a lot of them would tuck in their rank insignia and many did not wear any ranks on their smocks at all, even higher ranking FJ could be hard to distinguish from their enlisted counterparts while in combat gear.
