Quick answers
How do you slide in Battlefield 6?
Sprint and press crouch: Left Ctrl or C on keyboard, Circle/B on a controller. The game decides between crouch and slide from your movement speed, so binding both to one key is the intended setup.
How do you open the CommoRose?
Hold Q or the middle mouse button on PC, hold L1 on PlayStation or LB on Xbox. A tap places a ping; T on keyboard or R1/RB clears it.
How do you deploy a bipod or mount a weapon?
Press F on PC or click the right stick on a controller while prone or next to a surface the game marks as mountable. The same input is melee when nothing can be mounted.
What are the vehicle controls?
Ground vehicles use W/S to accelerate and brake, A/D to steer, Left Shift to boost, Z for the handbrake and Space or the left mouse button to fire. Aircraft and helicopters use W/S for throttle, A/D for yaw, the mouse or arrow keys for pitch and roll, and Right Ctrl or the left mouse button to fire. On a pad, triggers drive, sticks steer and aim, and the stick click boosts.
What is Uniform Soldier Aiming?
A setting that scales every zoom level from your hip sensitivity using a coefficient. With it on and the coefficient at 178, a flick that lands on a target at hip fire lands on the same target through any scope, which is why most players leave it on.
