i tend not to class war scenes as violent--don't know why, i think that it's because those are required in a war, whereas in a normal movie the violence is emphasised by the fact that it doesn't have to be committed.

some more violent scenes i've thought of:
the hammer and hook scenes in The Texas Chainsaw Massacre.
the end scene of soldier blue.
the child molesting scene in Sleepers--don't actually see it but it sounds distressing!
the killing of Stacks in Goodfellas--see the blood?
