Is there some rule of thumb to calculate airbursts?
Like multiply HE kill by X or similar?
I know there are already some airburst weapons in the game you could derive from but if there is already some semi official convention around I would like to know.
Thanks in advance.
There is one airburst arty round, and it has been around since I experimented with it for SP2. UK 105mm V/T. (I doubt I have bothered with it myself, since back then - better to buy a MLRS and get dual-effect ammo). Examining that round and the unitary 105mm LG should give you an idea, should you want to implement V/T in your own OOBs. Weapons 116 and 234.
