Probably men's refusing to respond at your commands after have been fired on heavily are panicked; leave them some time to recover.
Saluti and sorry for my english.
Agree with Sergei, i think is better to avoid too much control (micromanagement risk);
refining AI is the best choice IMHO
A real hunt command can be useful.
A method is to shot at first point, assign a short movement command and from this new position give an order to shot at another point and so on.
Works fairly for me.
