Need a little help with my game

Hi, I just recently started using Unity 5 and I have one question about my 2d game project.

Here is the problem:

As you can see my 3 soldier characters on the left side, I want to make their upper body always stay above the other one like the right side. Do I have to split my character into a part, like head, body and etc? or is there any way to do this as a single sprite?

Sorry for my bad English

Thanks!

Nevermind I found this tutorial!! Sorry for making this thread
