Each scenario comes in 2 versions: AFRF and USAF (and requirement both, and RHS:GREF). You undertake the same objectives, fight the same enemies, have the same number of squad members and follow the same route. You can choose to play as Americans or Russians. Each scenario will try to offer a comparable or equivalent list of equipment and assets, but there aren't always straight (or interesting) analogs between the two factions so where one faction might get two mechanized units, one might get an IFV and a tank.

Each mission will be fully working in singleplayer or in cooperative play, with the ability to respawn as a group member during multiplayer provided there are AI slots in the group. There will also be access to Virtual Arsenal, so those of you who don't like the weapons/equipment in RHS can substitute your own. Just note that doing so threatens to upset the game balance; some mods provide substantially more powerful versions of weapons, more/less protective armor, or let you carry more/less ammunition.

Some (all?) of these scenarios are enhanced by the ADAM mission maker http://www.armaholic.com/page.php?id=29232

For now every scenario takes place on Altis. This is subject to change as Bornholm, Esseker, Australia, Namalsk, and CUP terrains continue to be updated and if their performance improves.
