How do I make enemies walk as a group without going behind each other?

I am making a RTS game. So far I have made it possible to spawn soldiers in the game, and make them move to where you click on the map with the pathfinder behaviour.

Here is the problem. If I have multiple soldiers and I click on a location for them to move to, they all go to the exact same place. This means that they are now all behind each other, so it looks like there is only one soldier.

How do I make sure they avoid standing on the same place behind each other?

You can make them push each other: dropbox.com/s/4ahybqe3t0k758f/biters.c3p

I made something similar and I set their go to point to something within a range like x=random(mouse.x-30,mouse.x+30), y=random(mouse.y-30,mouse.y+30), this gave the effect of gathering in a spot but not overlapping.

If it needs to be really specific then you can decide where the positions are for the squad and assign each one an ID which is a specific position when you click, so the leader appears at mouse click, and the rest arrive at one of the other chosen positions based on their ID.
