BBC been running the promo for a couple of weeks. It looks like it's a different perspective on the Iraq War from what we've seen so far.
Clip:
..This isn’t a classic “Band of Brothers” tale of blood, bravery and comradeship under fire. It’s a powerful look at what happens to people who go to war and return to the surreality of real life, public buses, timecards, pubs and families who cannot understand the adrenaline rush of danger. It’s a modern twist on the 1946 classic “The Best Years of Our Lives”: these ordinary men who survived an extraordinary experience find reasons to return to the action.
