I've been playing around with an idea that revolves around foreign troops occupying some country (Could be Altis and Stratis, for an ARMA 3 slant) in a peace enforcement/counter-insurgency operation. Less to do with huge, wide-scale military ops or even special operations (the troops would be the regular rank-and-file) and more to do with just getting by without getting blown up by an IED, mortared by insurgents and trying to win over the local population. Sort of like a slice-of-life RP with a military setting.

You could use the idea if you want. I'd start up an RP like this, but I don't have the time, and seeing as how I'm going on a course to be converted to regimental police *coughglorifiedsentrycough*, I'm probably not going to find the time in the near future to run anything.
