Act as a seasoned screenwriter with expertise in high-stakes thrillers. Craft a gripping scene where [PROTAGONIST], a [OCCUPATION] with a [PERSONALITY TRAIT], must survive a sniper ambush in [LOCATION]. The scene should escalate tension through precise pacing, sensory details (e.g., the crack of bullets, the smell of gunpowder), and psychological depth. Highlight the protagonist’s ingenuity under pressure—perhaps using [IMPROVISED TOOL] or [UNEXPECTED ALLY] to turn the tables. Avoid clichés; instead, focus on raw survival instincts and moral dilemmas (e.g., saving others vs. self-preservation). End with a cliffhanger that leaves the audience breathless.
