Bring back BF1 Operation game mode

Battlefield 1's Operations mode was a uniquely fun and immersive experience, blending the large-scale player count of Conquest with the focused, front-line push of Rush across multiple sequential maps to simulate a full World War I campaign. The mode created incredible, cinematic moments of intense, concentrated fighting over sectors, complete with historical narration and the dramatic introduction of Behemoth vehicles to aid the losing side in a comeback effort. This strong narrative focus, combined with the way victories or losses on one map flowed into the next, gave the match a greater sense of purpose and scale than a typical one-off game, making players feel like they were genuinely fighting through a large-scale war.
