Top down Squad Based.

I and a group of friends are doing a game of squads top-down style, I would like to know the best way to create a squad with, for example, 4 soldiers, in which you select the whole squad, not one soldier at a time. If possible I would also like to know the best way to click on this squad and give simple orders, such as move to point A, making all squad soldiers go to that point. Thanks in advance for your help. And sorry for my English errors.
