Your problem is a micromanipulation problem. How to form a team is not the solution of micro-operation, nor is it the solution of controlling the team, because formation is the most taboo in micro-operation. If formation is used in micro-manipulation, it is difficult for the team to achieve the best offensive and defensive effect of formation. When micromachining, a single unit or two or three units are the basic operation objects, and the group formation operation mode must never be used. Even in a combat operation like Spider Stream, you can select similar units by double-clicking or dragging the mouse to select multiple groups of units, instead of using formation.

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.
