Only seen two of these (in bold) and I'm ashamed to say didn't finish the latter.
You watch quite a few military/war films, don't you? The Bridge
is probably too ordinary or clichéd for a typical war-film watcher.
If you want a similar premise but with a bit more action and perhaps a better dramatic flair, try 71: Into the Fire
. It's a South Korean film that revolves around a bunch of schoolboys defending a location. It has its flaws, but I found it rather entertaining. And *ahem* sad, of course, as it's based on a true story as well.
