Anti-Titan rifle

Marley's large-calibre rifle designed to hit Titans: Gabi uses it at Shiganshina to decapitate Eren with a single shot, a moment before his contact with Zeke.

Marley develops it when it realises Titans can be brought down by modern weapons. Gabi, raised as a Warrior candidate and an exceptional marksman, carries it to Shiganshina and with a single shot changes the course of the war.
