I also like the Command and Control module where you don't have to give orders to stacks of troops but can command platoons & sections much more easily.
Let me help you with that. Download this...

If you press 0 - 8 while playing, a menu system will pop up that will hopefully improve the HC game for you. The first option is the QUICK COMMANDS menu. This one is to be used when in HC mode. Select one or more units to command, then select the command on the menu. The most useful are the HALT and PROCEED commands. Using these, you can make elaborate plans without having the various squads moving as soon as an order is given...much better for making coordinated attacks. The SQUAD LEADER menu basically gives you the chance to switch to any squad member in your current squad, with a few other functions. Finally, the COMMUNICATIONS menu lets you shut everyone up!
Here is a more complex scenario with more advanced menus. Feel free to load it up and play around with it. It is not complete, but it is certainly playable.
