The opening to The Kingdom:

That of Operation Flashpoint: Dragon Rising, similiar, if a little far fetched:

The opening of Ghost Recon: Desert Siege, too. And, of course, 'The Hudson River, two years ago...'.
Oh! - the opening of the excellent The World at War. Sadly, I can't find a video. It is very sombre, sets the tone brilliantly. Sir Laurence Olivier narrates to silent footage of
Oradour-sur-Glane:
Down this road, on a summer day in 1944... the soldiers came. Nobody lives here now. They stayed only a few hours. When they had gone, the community which had lived for a thousand years... was dead.
This is Oradour-sur-Glane, in France. The day the soldiers came, the people were gathered together. The men were taken to garages and barns, the women and children were led down this road... and they were driven... into this church. Here, they heard the firing as their men were shot. Then they were killed too. A few weeks later, many of those who had done the killing were themselves dead, in battle.
They never rebuilt Oradour. Its ruins are a memorial. Its martyrdom stands for thousands upon thousands of other martyrdoms in Poland, in Russia, in Burma, in China, in a World at War...
At the village of Oradour-sur-Glane, the day the soldiers came, they killed more than six hundred men, women... and children. ...REMEMBER.
Do-do-do-de-do...
