what you could do is film your 10 soldiers in front of a green screen. Then using Trapcode's
particular have your particle set to custom and use your keyed green screen footage as the source layer! then adjust the rest of particulars settings in accordance with your scene!
Another way would be to film your 10 soldiers over and over again doing various movements and so forth then bunlde all these shots into one scene placed as how you would see fit!
hope this helps!
