The free-form campaign rules included within Force on Force have me hooked. Small scale, simple, encourage play and feed results straight back into the next game. Reminiscent of FAD v4. I played them campaign through on paper a couple of times and found it reminded me of the excerpt from "War" by Sebastian Junger I read last summer in one of the saturday broadsheets.
as a result created the small break away province of Slavikova within Eli's Crisis in Alcovia blog. Where the militias have taken over and the region needs to be brought back under control.
What I particularly like is the fact that there's no one size fits all approach. The campaign can be played from either a "regular" or insurgent perspective, where you get to build the insurgency through your military prowess on the battlefield. Needless to say, lot's of potential for a Ghost Recon style campaign, chronicling the headaches of Starshina Grojny and his Motor Rifle Platoon, plus near future, post apocalypse and military orientated Fi settings.
