Pros
You'll work with some great people, both colleagues and client personnel. Some of your bosses will be really great, too, [but some others won't enforce their humanity on the corporation, and will instead accept the mentality of SCIS, and thus they'll treat you like they own you. Some will become so exasperated with the constraints and demands placed on them in the "bad management pincer" (crazed client firm, together with the insanities of SCIS "management") that they will become moody, somewhat crazed, and/or give up trying. I've seen it repeatedly: 5 site managers in about as many years.] You can use SCIS to help you to the next step in your career, in one or both of two ways: 1. Getting to know the client company and its personnel, and using that to access opportunity there; 2. Getting a security clearance and accesses while you're working on #1 (acquaintance with company and personnel). Don't be shy about that; just be prudent and do right by your country and your best sense of virtue and dignity. Aim for an excellent company to wash off the SCIS stain (use-use relationship) from your sense of self afterwards.
Cons
Working for a company that acts like a recalcitrant 13-year-old, trying to (and too often succeeding to) get away with everything he thinks he can get away with, and not taking care of ANYTHING--not people and not even inanimate assets. And then blaming YOU when things break down. I managed to avoid that latter being aimed at me, but I sure watched it get aimed at others a lot. I could get into specifics, but suffice to say that the executive offices of SCIS need a ... at the very least a philosophy transplant. This would in turn cause a much-needed revision of policy, practice and systems (including the poorly managed and/or programmed computerized/data management systems).
