I have been working on these forces for a while now, originally intended for use with Dirtside but can easily fit into the FWC setting.
http://s939.photobucket.com/albums/ad234/Gunhit... The NSL (New Swabian League) will have the Rommel MBT as its main MBT supported by a pair of Warhounds. I intend getting some DRM vehicles for IFV's and artillery and will mix in some Imperial Guard "stormtroopers".
The ESU (Eurasian Union) will be MBT/Mech based with GEV and GW Vultures for infantry delivery. Artillery will be remote Missile Pods or BT Thumper guns.
T.A.U (??) this is a mid-tech Alien force I have started building just to make use of the various BT vehicles I had. No mechs in this force, but may see a few Massive units like the BT "Behemoth tank".
Also working on a Android force using yet more BT vehicles with ADLER Kfir infantry.
