Specialties V4.0

[kcdusk]

I'm creating some PCs in V4.0. The rulebook says PCs can start with a specialty. I'm assuming this means one only, i haven't been able to find anything in the Ref or Player manual that suggests otherwise.

One of my PCs is an experienced A grade operator. I've given him 4 specialties (ranger, navigation, scout and infiltrator).

How have you dealt with specialties in your games? Have you limited it to one per PC? How many specialties would you give a high level experienced PC and still keep it "real"?

As stated, i've given out 4 specialties to represent a form of sniper/behind enemy lines kind of operator - but have stopped from giving them +1 specialties for firearms.
