One thing that Battlefield 1 seems to lack are squad leaders that actually lead the squad. How often have you sat and requested orders from your leader only to receive none? It's probably a lot.

Fortunately, DICE is aware that people want the mutiny feature back. A DICE developer posting on Reddit said that the feature from Battlefield 4 will be making a return very soon.
Heya, this is one of the most requested features. It will be fixed in one of the upcoming patches. Basically following the BF4 standard where if a squad member request an order and does not receive any, that squad member will be promoted to leader.

Keep in mind that a solid date for when this will be implemented is not yet known. There is an update coming in about 40 minutes for all platforms. We'll have details on what is included later on.
