Moving multiple AI units as one for RTS game.

I have a single AI unit that will path find to wherever the player clicks in the world. That works perfect. I need help moving multiple units with one click as if they are one. I want to be able to click somewhere and have multiple units move there. I don’t care to be able to control each unit individually but I want them to each path find as if they are individual if that makes any sense. Any help I could get would be great, thanks in advance!

There are several ways games accomplish this, what you do is make a target when you click on the map and you use that as the goal for all your troops. Some use the A* method but that can cause clogging, so what a lot of modern rts games are doing is using flow fields. Supreme Commander takes this approach. If you have the money you can purchase my rts movement system on the asset store. It has troop selection, hot key grouping, flow fields to direct movement. It should be a great start for an rts game.
