In the Specialist Equipment of the Comissar it says that they wear Commissar's Uniform. Does this mean that they don't have Flak vests/full body armours as the soldiers they fight along with? Are there specific stats for this Uniform in the book (I can't seem to find anything like this)?
The same happens with the Ministorum Priest, which specialist equipment entry specifies that wears Eccleasiarchy Robes.
How do you manage this? Some types of armour don't look "cool enough" on some characters, but are quite useful. The same applies to Space Marines and their helmets: it looks cool to be a space marine without a helmet, but it's kind of silly to expose yourself in that way to enemy fire.
