Life is beautiful, war is hell. Who loves the smell of napalm in the morning? Whether you’re on the frontline or the home front, we want you to advance your 10 greatest war films. From satirical comedies to dam-busting schemes, doomed romances to epic homecomings, the war movie canon is an incredible cross-genre minefield. Base your list on any criteria: strength of character, evilness of enemy, realism of military life, implausibility of plan… and tell us why in the notes. Take your time: Showdown is going fortnightly from here on in (and send us your topic suggestions). They may take our lives, but they’ll never take our freedom.
