The Regimental March of the Parachute Regiment, don't you know!

I have only seen clips from the "'Ridge" ... but they were indeed good.
Myself, I prefer the more understated style of British (as opposed to Hollywood) war (or war-related) films.
"Bridge Over the River Kwai" (1957)
"The Hill" (1965)
"The Guns at Batasi" (1964)
"Ice Cold in Alex" (1958)
... to name but a few.
PS: there was a bloke like Doss at Gallipoli in the earlier World War - whose name, I regret to say, escapes me just at the moment.
