The bumper sticker description of this project is 'see first, understand first, act first and finish decisively,' and while Boeing's official FCS site doesn't have a lot of technical details, but you can find some good information at Global Security. To quote their page, "FCS is envisioned as a networked 'system of systems" that will include robotic reconnaissance vehicles and sensors; tactical mobile robots; mobile command, control and communications platforms; networked fires from futuristic ground and air platforms; and advanced three-dimensional targeting systems operating on land and in the air.' The Phase 2 request for proposals just appeared and the estimated price is $26 billion through fiscal year 2009. The fact that the Army is spending billions of dollars on a project isn't anything new, but a little known fact is that the OS for FCS will be Linux (FAQ 4 here.)"
