Greetings all:
Well, I've come across a couple of things that have helped me in the past on creating missions.
First one is a codename generator. it's really cool, select your country of operations and type and it randomly creates names for you, it's pretty cool.
Codename GeneratorThe next one is a manual on battle command operations. It gives you insight on how to create realistic missions for OFP and ArmA...
Battle Command ManualI hope that helps. I know the 2nd link has been in the BIS forums, but hey I'm sure people don't know about it or not everyone.
Cheers,
NightJay
