Here's the infantry for my current (and last?) 15mm army. HALO theme. Perhaps a bit simple, but it pretty much has to be simple these days for stuff to get done. Miniatures are Critical Mass, Khurasan, and Blue Moon.
This is another 15mm army I painted just before we moved into the house. It's a high-tech army with grav vehicles meant to fight my Sahadeen army ( Sardaukar from the Dune series was inspiration) . Infantry are Blue Moon. Vehicles are GZG and Combat Wombat.
