Rainbow Six Siege coaching is a one-on-one session with a Champion or pro-level player who watches how you play, names the habits costing you rounds, and gives you a plan to fix them. It covers the whole game, not just aim: drone usage, site setups, utility timing, mid-round reads, rotations, and post-plant positioning.
Sessions usually run in two formats. Live coaching means you queue ranked while a coach watches your screen share on Discord and talks you through the round as it happens, calling the swing you shouldn't have taken or the wall you shouldn't have reinforced. VOD review means your coach pulls up a recent match, scrubs to the moments the round was actually decided, and explains what to do differently.
You'll think you lost the round in the last ten seconds of a 1v1, and your coach will point to the drone you burned in the prep phase that left you blind for the entire push.
No coach ever logs into your account. You still put in the games, just with direction.
