Please watch the videos of experts from the first-person perspective and see how professional players fight against micromanipulation. It is the premise to improve micro-operation through continuous insight into professional players, the means to improve micro-operation through practicing micro-operation charts or continuous actual combat, and the means to improve hand speed through continuous combat. Try to micromanage the war to each unit and let each unit do its job. If you can't do this for the time being, please don't use formation to do battle micro-operation first.
There is no need for formation micro-operation, and each soldier or each group of soldiers needs to be operated separately (for example, two or three big G's attack on a squad), without omission. Practice is essential.
