I don't know Ghost recon. but I sure approve the FPS approach far more than the Sims / Warcraft / FF action scenes.
However, I think it would be even better to adopt "near-FPS" sights, close "third person" I mean, and GROUP sights ( / hearing ) as well.
The system used in ICO is very good for the usual sight distance (lets you recognize your charz AND perceive a lot of your surroundings) and the zoom effects (lets you see - even a little in the cinematic cuts - details, faces, surroundings details).

And more than in "missions", I believe in contexts / scenarios / stories.
That is : the player doesn't choose the quest / mission, but he/she simply has to "roll with the blows" and make the Wolfriders survive the (surprise) events...
