Yes and no. All Earthforce uniforms in this division are blue; EA
marines are olive/brown; security and other NCO areas get grey. Within
those areas, it's further subdivided, and is distinguishable by the
horizontal bars below the EA insignia. Gold is command; silver is for
command staff. (Ivanova, being in between, has a divided bar, half gold
and half silver.) Red is medical, green is security. Yellow is for
science division. The rank bars are on the shoulder.
