@DragotheWolf,
1. Restrepo (2010) - A year in the shoes of a platoon in Afghanistan who erect a new operating base called "Restrepo", named after a fallen comrade. The team takes fire almost everyday, from mortars to machine gun. I heard the director was shot an killed in Libya while filming a new doc.
2. The War Tapes (2006) - Three members of a U.S Army unit carry cameras on their helmets and record a year in Iraq. As they guard KBR trucks from fire, witness real IED attacks, fire fights and a few humorous moments to do with waste trucks.
3. Gunner Palace (2005) - A US platoon takes over a former palace owned by one of Saddam's sons. Here they use it as a base while performing their duties as soldiers. A few fire fights, mortar attacks and a lot of one on one with the members of the unit themselves.
4. Why We Fight (2006) - A doc aimed at all the elements of war from the bomb makers themselves, to former members of the frontlines. Trying to look deep into the psychology of why we go to war, it features a very interesting historic speach by Eisenhower. Very imformative.
5. No End In Sight (2007) - Referring to the end of the Iraq occupation, a very deep look into what went wrong with the invasion of Iraq, who is responsible and who stood to make the most money. Top Notch.
