John Ford's Masterpiece of the Frontier!

Owen Thursday sees his new posting to the desolate Fort Apache as a chance to claim the military honour which he believes is rightfully his. Arrogant, obsessed with military form and ultimately self-destructive, he attempts to destroy the Apache chief Cochise after luring him across the border from Mexico, against the advice of his subordinates.
Fort Apache keeps every mind human — it fights its subject at zero distance. The story fights on E8/E9/E11 of the E0–E14 reality ladder.
Films fighting at the same level of reality, about the same things.
