You dont need the ; semicolon at the end.
You also may need CBA, as alot of mods require it, get it here:
Once you install CBA_A3 then your target line will look like this:
-mod=@CBA_A3;@NATO_Russian_SF_Weapons v1.0;@African_conflict_A3_v1.0;@asdg_jointrails;@fhq _accessories;@sud_russians_v34;@RH_Pistols
me personally I would trim the names a bit an example:
Also a launcher like this:
makes setting up mods to run with the game very easy, i use that particular one all the time. But as for your mods just make sure all of them are in your arma3 directory, and any userconfigs that come with those mods should be there too.
hope that helps.
ps. where you at in Illinois?
as I live in the state as well.
