Here's an update.
I find that simply allowing your squad to understand your tactical role makes them not only follow the plan, but fight with aggression not seen in the rest of your team.
Essentially, this tip is on how to create a crack team. It doesn't take hours of training together, although it helps to work with individuals who are great at some specific things like sniping, or mg etc.
Still, this goes for even averagely skilled players like myself.
If you decide to hold a building on the flanks rather than simply plough into the enemy with the rest of your army, and you can communicate why doing so is what is actually turning the battle, your men won't need to be micro managed.
Indeed, they start to take initiate themselves in a way which funnels into your strategy.
