You can use duplicate to create copies of Poser content (maybe a good feature request?).

You can use only two good ways to duplicate:

 

1 - Using Replicator or Surface Replicator, this will create new instances but always in the same pose.

2 - You can create your character and drag it to the Objects tab in the Browser to use later. This way you can load it as many times you want and your memory alows. Is the best way to work.

If you are doing some illustration a trick is to render the soldiers in the background separeted and join all in Photoshop or another 2D paint peogram.
