The landwarrior is an ambitious concept, but I don't see the need to network every soldeir to the rest of the force. I can see having each squad leader having this system equipped, but not every soldier, it is just too much crap that gets in the way for the ordinary rifleman.
However, I found this line to be the most disturbing from the first article:
"Videogames, even those with "Tom Clancy" in the title, aren't known for their realism..."
The article goes on to say how [GR] was realistic, but that line hit a nerve in me.
